How much does an apple sapling cost? How many years after planting? How do you produce high yields?

Apple is one of the very familiar and indispensable fruits in our life. Some people say that one apple a day will keep the disease away from me. It is true, but if you want to plant successfully, you need some skill. How much is the apple sapling? How many years after planting? How to grow high yield?

How much is an apple sapling?

A columnar apple seedling is about 30 ~ 50 yuan. The prices of different varieties will be different in different regions. Please consult your local farmers market for details.

How many years will it turn out?

Generally, apples begin to bear fruit only after 2-3 years of planting. The fruit growth period was 65-87 days for the general early-maturing varieties, 90-133 days for the middle-maturing varieties and 137-168 days for the late-maturing varieties. In general, apples can have a lifespan of 15-50 years after planting.

Apple sapling planting:

1. New orchards

All new rootstocks and new varieties are adopted, and apple seedlings are recommended to have high wild degree, strong soil adaptability, disease resistance, drought and flood resistance and long life span. In order to improve the quality of newly-built orchards, strict soil preparation and adequate bottom fertilizer are applied, fixed value pits are dug according to the required density before planting, the specification is 0.6mx0.6m depth of 0.6m, subsoil and topsoil are separated, and bottom fertilizer / mu fertilization (organic fertilizer) 1500kg~2000kg is applied. According to the local soil, more organic fertilizer with fine sandy soil can be applied (0.1kg potash fertilizer 0.2km compound fertilizer 0.2kg can be added with a small amount of nitrogen fertilizer) and topsoil can be mixed and backfilled with ground 15cm, trample, make full use of land resources, plant row spacing is 2m x 2m, planting ditch 0.6mx0.6m can also be dug, irrigation is carried out in holes 3-4 days before planting, and soak in solution with 700x methyl tophan or 500x carbendazim for one day and night before planting. Make it fully absorb water and disinfect the seedlings. After soaking, the roots of the seedlings are dipped in the mud equipped with rooting powder, watered in time after planting, covered with plastic film to moisturize, and drained in time to prevent the seedlings from yellowing and dung loss.

2. Seedling shaping and pruning

Mainly advocate spinning shape. The result of the spinning shape is relatively early, and it is a kind of tree shape advocated at present, with a height of 2.5 to 3. With a crown width of 1.8 meters and a stem height of 70 cm, there are 10-15 main branches evenly on the central trunk, regardless of layers, the spacing between the main branches is 15-20 cm, evenly distributed around, the opening angle of the main branch is 60-90 degrees, this kind of tree-shaped crown is small and easy to manage, flowering in the same year, fruiting in two years, and the production can be greatly increased in three to four years. Seedling pruning is mainly plastic surgery, which is generally carried out in early spring, leaving none of the skirt branches below the trunk 70cm, one for each 20cm above 90cm, to choose a good direction, the growth length is not cut in 80cm, all are flattened and sprouted, 50~30cm is cut to promote new branches, and the central trunk is not cut short in the coming year, but a knife is cut every 20cm ring to promote the uniform growth of branches. From May to June, it is necessary to twist the top in time, control the heart, and cut the trunk of the robust tree to promote the differentiation of flower buds. If the branches are too exuberant, they can be treated with paclobutrazol to control the growth of branches and promote the increase and fullness of flower buds.

3. Pruning fruit trees

Spring pruning: from sprouting to flowering, pruning tasks are completed by means of bud wiping, branch thinning, retraction, sprouting, ring peeling and other measures, and pruning tasks such as branch pulling are also included in young orchards.

Summer pruning: the techniques of opening angle, coring, twisting, ring peeling, thinning and ring cutting are adopted to ease the tree potential, improve the light and expand the crown.

Autumn shearing: through drawing branches, thinning erect branches, growing branches, dense branches and over-dense peripheral shoots and other measures to improve light conditions, promote flower bud differentiation, and improve the cold resistance of trees.

Pruning during the dormant period

It is pruned from falling leaves in winter to before sprouting in spring. The main task is to remove some useless branches, such as disease and insect branches, dense branches, overgrown branches and so on. The method is to cut short backbone branches, retract over-large fruiting branches, auxiliary branches and weak backbone branches. Its function is to adjust the angle and extension direction of backbone branches, auxiliary branches and fruiting branches, control the proportion of flower leaves and buds, and balance tree potential, so as to achieve the purpose of high yield and high yield.
