The thickness of fruit branches has little effect on the fruit, the color is above 75% or even all red, and it is self-flowering, and the peach yield per mu is above 5000KG in the full fruit period, which is a new super-high yield variety.
About 66 plants are planted per mu, and the mature season coincides with Mid-Autumn Festival and National Day Festival, so the market potential is huge. Mid-Autumn red peach with beautiful appearance, large fruit and excellent quality is positioned to visit relatives and friends in the Mid-Autumn Festival, and its commodity value in Jinxiang and surrounding counties and towns is higher than that of similar products.
Cultivation of Mid-Autumn Red Peach
Peach trees are planted in autumn and spring, 1 65438+1October1till the following March 15.
Generally, there are about 66 trees per mu according to the point value, leaving some roads to dig ditches.
The diameter and depth of the planting pit are generally 80- 100 cm, and farmyard manure should be applied well.
The diameter of seedlings sold in two years is about 0.7 to 1.0 cm.
Pay attention to pruning, watering, fertilization and pest control of peach trees.
Rational use of land, two years before planting, other crops can be planted between rows, paying attention to not competing for fertilizer and not inducing pests and diseases.
Water and Fertilizer Management of Mid-Autumn Red Peach
Generally in late June, 10, mainly decomposed farmyard manure,
Peach trees have shallow roots, mostly distributed in 20-50 cm soil, and the fertilization depth is 40 cm. When applied to annular and radial gullies, the width and depth of the gullies around the crown are about 30-40.
Fertilization should avoid big tree roots, farmyard manure should be decomposed, and the soil can be turned once a year.
Peach trees like light and are afraid of waterlogging. Pay attention to ridging when planting and drain water in time after rain.
Peach trees need more potassium fertilizer, and if the PH value is too high, iron deficiency and yellow leaves are easy to appear. Pay attention to two points and reasonably increase the application of iron, potassium and nitrogen.
It is more effective to spray foliar fertilizer once a week one month before peach trees mature.
In mid-September, apply organic fertilizer and add appropriate trace elements to prevent element deficiency. After clearing the orchard from late September to before defoliation, some overwintering pests will be eliminated, leaves will be protected, and roots will be raised to strengthen trees.
Pruning of Red Peach Fruit Trees in Mid-Autumn Festival
Short cutting in winter: cutting branches short to produce new branches and increase the number of branches. Divided into 1/2 short nodes, the new branch is better than the lower branch; 2/3 short section, used to trim the extension head of the main side branch; 3/4 short cut, sprouting branches grow vigorously, used for extending branches or pruning long branches and middle fruit branches; The two buds at the base were cut off and made into branches, which should be cut before the severe winter of 65438+February.
2. Pruning in summer: The main purpose is to inhibit the excessive growth of new shoots, promote the differentiation of flower buds, increase the branching order and improve the lighting conditions, thus improving the fruit quality. Summer pruning can be carried out in the whole growing season, including budding, coring, pruning, twisting and pulling branches.
(1) Wipe off buds When the sprouting branches on the branches grow to 3-5cm in spring, erase 65,438+0-2 of the double buds and the third buds, and erase the competitive buds under the incision and the clustered buds in the crown cavity. By removing buds and sprouting, useless new shoots can be reduced, nutrition can be concentrated, and the remaining branches can be fully developed; It can improve the lighting conditions of the tree crown and reduce the workload of pruning in winter and the wounds caused by thinning branches in winter.
(2) Core removal is to remove the tender parts at the top of branches. Kerning can change the distribution of nutrients, which is beneficial to the enrichment of branches. Kerning is often used to control the growth of competitive branches and long branches. When the length of each main branch reaches 50 cm, it can be cultivated into a secondary main branch in one year.
(3) The new buds grow too fast, so they can't be cut when coring. Fruiting branches can be produced by pruning from mid-May to June, and the pruning length is 3 ~ 5 leaves at the base of flourishing branches. Thinning can be carried out after July, and the outer branches and upper branches can be removed.
(4) Twisting branches For upright branches with vigorous growth, when the lower part of new branches begins to lignify in the middle and late May, pinch the semi-lignified part with your fingers and twist it to the gap of the tree, so that the new branches become horizontal or drooping, so as to slow down the growth of the top and transform the long branches into fruiting branches.
⑤ Pulling branches can open corners, ease tree vigor, improve lighting conditions and prevent baldness at the lower part of branches. Branching is usually carried out in May-July, and the object of branch pulling is auxiliary main branches or large branches. The branch pulling angle is 60 ~ 70 degrees.
Mid-autumn red peach thinning fruit
Remove deformed fruit, double fruit and small fruit. Trees should leave more fruits on the upper bearing branches, less fruits on the lower bearing branches, more fruits on prosperous trees and less fruits on weak trees.
Generally, long fruit branches have 2-3 fruits, middle fruit branches 1-2 fruits and short fruit branches 1 fruit. Fruit spacing 15-20 cm, generally one fruit 15 leaves, and 500-700 fruits are thinned in full fruit stage. Weak fruit branches and flower branches do not bear fruit, and preparatory branches do not bear fruit.
Take the method of thinning fruit without thinning flowers, thinning fruit 1/3 two weeks after flowering, setting fruit 5-6 weeks after flowering, and ending before the hard core stage.
Pay attention to the vigorous growth of fruit trees in the first three years, rationally distribute the nutrients of fruits and branches, and prevent fruit drop symptoms due to vigorous growth. Therefore, the new shoots of branches should reach a foot long.
Bagging and unpacking of Mid-Autumn Red Peach Fruit
1, June 1 fruit bagging,
2.8 months 1 day.
3. Fruit trees are flourishing, which easily leads to luxuriant leaves and affects the demand for light after fruit bagging.
Shading leaves can be removed appropriately.
Six, Mid-Autumn Festival red peach fruit tree pest control
1, control peach moth, leaf roller, spider mite, stink bug, scab, bacterial perforation and brown rot in the middle and late July.
2. Prevent leafhoppers, bedbugs, scab and brown rot. Due in the first half of September.
3. Spraying fungicides and pesticides before bagging peaches to prevent pests and peach rust.
