Soil Culture. J. H. WaldenЧитать онлайн книгу.
trees, however, are thought to last only about fifty years. An apple-tree, imported from England, produced fruit in Connecticut at the age of two hundred and eight years. The apple is the most valuable of all fruits. The peach, the best pears, the strawberries, and others, are all delicious in their day; but apples are adapted to a greater variety of uses, and are in perfection all the year; the earliest may be used in June, and the latest may be kept until that time next year. As an article of food, they are very valuable on account of both their nutritive and medicinal qualities. As a gentle laxative, they are invaluable for children, who should always be allowed to eat ripe apples as they please, when they can be afforded. Children will not long be inclined to eat ripe fruit to their injury.
An almost exclusive diet of baked sweet apples and milk is recorded as having cured chronic cases of consumption, and other diseases caused by too rich food. Let dyspeptics vary the mode of preparing and using an apple diet, until it agrees with them, and many aggravated cases may be cured without medicine. It is strange how the idea has gained so much currency that apples, although a pleasant luxury, are not sufficiently nutritious for a valuable article of diet. There is no other fruit or vegetable in general use that contains such a proportion of nutriment. It has been ascertained in Germany, by a long course of experiments, that men will perform more labor, endure more fatigue, and be more healthy, on an apple diet, than on that universal indispensable for the poor, the potato. Apples are more valuable than potatoes for food. They are equally valuable as food for fowls, swine, sheep, cattle, and horses. Hogs have been well fattened on apples alone. Cooked with other vegetables, and mixed with a little ground grain or bran, they are an economical food for fattening pork or beef. Sweet or slightly-acid apples, fed to neat stock or horses, will prevent disease, and keep the animals in fine condition. For human food they may be cooked in a greater variety of ways than almost any other article. Apple-cider is valuable for some uses. It makes the best vinegar in general use, and, when well made and bottled, is better than most of our wines for invalids. Apple-molasses, or boiled cider, which is sweet-apple cider boiled down until it will not ferment, is excellent in cookery. Apple-butter is highly esteemed in many families. Dried apples are an important article of commerce. Green apples are also exported to most parts of the world. Notwithstanding the increased attention to their cultivation during the last half-century, their market value is steadily increasing, and doubtless will be, for the best varieties, for the next five hundred years.
It does not cost more than five or six cents per bushel to raise apples; hence they are one of the most profitable crops a farmer can raise. No farm, therefore, is complete without a good orchard. The man who owns but five acres of land should have at least two acres in fruit-trees.
Soil.—Apples will succeed well on any soil that will produce good cabbages, potatoes, or Indian corn. Land needs as much manure and care for apple-trees as for potatoes. Rough hillsides and broken lands, unsuitable for general cultivation, may be made very valuable in orchards. It must be enriched, if not originally so, and kept clean about the trees. On no crop does good culture pay better. Many suppose that an apple-tree, being a great grower, will take care of itself after having attained a moderate size. Whoever observes the great and rapid growth of apple-trees must see, that, when the ground is nearly covered with them, they must make a great draft on the soil. To secure health and increased value, the deficiency must be supplied in manure and cultivation. The quantity and quality of the fruit depend mainly on the condition of the land. The kinds and proportions of manures best for an apple-orchard are important practical questions. We give a chemical analysis of the ashes of the apple-tree, which will indicate, even to the unlearned, the manure that will probably be needed:—
Analysis of the ash of the apple-tree.
This table will indicate the application of plenty of wood-ashes and charcoal; lime in hair, bones, horn-shavings, old plaster, common lime, and a little common salt. Lime and ashes, or dissolved potash, are indispensable on an old orchard; they will improve the fruit one half, both in quantity and quality.
Propagation.—This is done mainly by seeds, budding and grafting. The best method is by common cleft-grafting on all stocks large enough, and by whip or tongue grafting on all others. (See under article, Grafting.)
Grafting into the sycamore is recommended by some. The scions are said to grow profusely, and to bear early and abundantly; but they are apt to be killed by cold winters. We do not recommend it. Almost everything does best budded or grafted into vigorous stocks of its own nature. Root-grafting, as it is termed,—that is, cutting up roots into pieces three or four inches long, and putting a scion into each—has been a matter of much discussion and diversity of opinion. It is certainly a means of most rapidly multiplying a given variety, and is therefore profitable to the nurseryman. For ourselves, we should prefer trees grafted just above, or at the ground, using the whole stock for one tree. We do not, however, undertake to settle this controverted point. Our minds are fixed against it. Others must do as they please. Propagation by seed is thought to be entirely uncertain, because, as is supposed, the seeds will not reproduce their own varieties. We consider this far from being an established fact.
When grafts are put into large trees, high up from the ground, their fruit may be somewhat modified by the stock. There is also a slight tendency in the seeds of all grafts to return to the varieties from which they descended. But we believe the general rule to be, that the seeds of grafts, put in at the ground and standing alone, will generally produce the same varieties of fruit. The most prominent obstacle in the way of this reproduction is the presence of other varieties, which mix in the blossom. The planting of seeds from any mixed orchard can never settle this question, because they are never pure. Propagation by seeds, then, is an inconvenient method, only to be resorted to for purposes of acclimation. But it is so seldom we have a good bearing apple-tree so far removed from others as not to be affected by the blossoms, that we generally get from seeds a modification of varieties. Raising suitable stocks for grafting is done by planting seeds in drills thirty inches apart, and keeping clear of weeds until they are large enough to graft. The soil should be made very rich, to save time in their growth. Land where root-crops grew the previous year is the best. If kept clear of weeds, on rich, deep soil, from one to two thirds of them will be large enough for whip-grafting after the first year's growth. The pomice from the cider-mill is often planted. It is better to separate the seeds, and plant them with a seed-drill. They will then be in straight, narrow rows, allowing the cultivator and hoe to pass close by them, and thus save two thirds of the cost of cultivation. The question of keeping seeds dry or moist until planting is one of some importance. Most seeds are better for being kept slightly moist until planted; but with the apple it makes no difference. Keep apple-seeds dry and spread, as they are apt to heat. Freezing them is not of the slightest importance. If you plant pomice, put in a little lime or ashes to counteract the acid. For winter-grafting, pull the seedlings that are of suitable size, cut off the tops eight inches from the root, and pack in moist sand in a cellar that will not freeze. After grafting, tie them up in bunches, and pack in tight boxes of moist sand or sawdust.
Transplanting.—This is fully treated elsewhere in this work. We give under each fruit only what is peculiar to that species. In mild climates transplant in the fall, and in cold in the spring. Spring-planting must never be done until the soil has become dry enough to be made fine. A thoroughly-pulverized soil is the great essential of successful transplanting. Trees for spring-planting should always be taken up before the commencement of vegetation. But in very wet springs, this occurs before the ground becomes sufficiently dry; it is then best to take up the trees and heel them in, and keep them until the soil is suitable. The place for an apple-tree should be made larger than for any other tree, because its roots are wide-spreading, like its branches. The earth should be thrown out to the depth of twenty inches, and four or five feet square, for an ordinary-sized tree. This, however, will not do on a heavy clay subsoil, for it would form a basin to hold water and injure the tree. A ditch, as low as the bottom of the holes, should extend from tree to tree, and running out of the orchard, constructed in the usual method of drains, and, whatever be the subsoil, the trees will flourish. The usual compost to manure the trees in transplanting will be found elsewhere. In the bottom of these places for apple-trees should be thrown a plenty of cobblestones, with a few sods, and a little decaying wood and coarse manure. We know of nothing so good under an apple-tree as small
