Cultivation techniques of Jinxiang yellow peach 1;

(1) Jinxianghuangtao has no pollen, so attention should be paid to the configuration of pollination trees during cultivation. The pollination varieties can be Jinxiu Huangtao and Bumuzaosheng.

(2) The growth potential of young trees is strong. Pay attention to the widening of the bottom angles of main branches and lateral branches, and appropriately reduce the growth slowdown and tree potential, so as to make them bear fruit early and increase yield.

(3) At the initial stage of fruit bearing, the medium-long fruit branches were dominant, and the tree turned gently at the full fruit stage, and the proportion of medium-short fruit branches increased. Therefore, we should pay attention to cultivating and selecting long, medium and short branches with rich and strong growth according to different tree ages.

(4) Putting a layer of yellow-brown single-layer bag on the fruit after thinning can make the peel more shiny and beautiful.

2. Cultivation techniques of Jinxiu yellow peach;

Splendid peach seedlings are usually planted from June 1 1 to March of the following year, mainly in autumn, and planted before the soil is completely frozen after defoliation, so that seedling emergence is delayed quickly and the survival rate is high next spring. Choose robust seedlings (try to choose one-year-old seedlings, which is shorter than the period with buds 1 year, and the molding is shortened by 2 years, and the fruit can be produced in the second year). Remember not to plant it too deep, but shallow. Before planting, the stem must be cut off (leave half above the joint and cut off above).

When the seedlings are buried in 1/2 soil, lift the seedlings upward to allow the roots to fully extend, then fill the soil and water it, and it is best to cover it with plastic film. The traditional plant spacing is 3m× 4m, and 55 plants are planted per mu, adopting a tree type with three main branches (leaving three main branches to expand around happily).

Extended data:

Yellow peach is a very delicate fruit variety. In order to ensure the excellent quality of yellow peach, ecological control methods should be adopted as far as possible to control pests and diseases.

1. Choose a garden?

According to the principle of suitable land and suitable trees, the garden is located in Qianjin Tian Village (formerly Jingudui Village), Pengta Township, Huoqiu County, east of East Lake and west of Pi River. The landform type is hilly, the slope is below 25, the soil parent material is Xia Shu loess, and the soil is sticky yellow brown soil, with wide terrain, convenient water use and transportation, and the groundwater level is below 1 m?

2. plow the fields?

Ploughing the garden can improve the soil structure and increase the oxygen content in the soil, which is beneficial to the growth and development of Jinxiu yellow peach and enhance the ability of fruit trees to resist pests and diseases. The tillage depth is suitable and should be completed before the soil is frozen. When plowing, sharp instruments can kill some pests in the soil, or turn the overwintering pests in the soil to the surface for birds and their natural enemies to eat, or freeze to death or dry to death.

At the same time, ploughing can also turn weeds and fallen leaves on the soil surface into the soil, increase the source of fertilizer and improve soil fertility. ?

3. Trim branches?

In order to promote the growth and development of trees and form full branches, young forests should be lightly pruned, branches of pests and diseases should be pruned, excessive growth of trees should be controlled, and natural round-headed happy crowns should be gradually cultivated. ?

4. Fruit management?

In order to improve the fruit setting rate, amino acid foliar fertilizer should be sprayed 1 time when the bud is red, the flowering period and the young beans are big, but less fertilizer should be applied before flowering to prevent the new shoots from running off. Appropriate fertilization can be used for rehabilitation in summer; To prevent water accumulation in rainy season, timely drainage, to prevent pests and diseases.

The fruit thinning time is from 14 d after flowering to hard core stage. The specific methods are as follows: first, from top to bottom, from inside to outside, first remove small fruits, pests and diseases, fruits on leafless branches and abnormal fruits, and choose the fruits that grow downward and on both sides of fruit branches; The fruit spacing on the same fruit branch is 4 ~ 5 cm, weak fruit branches and backup branches generally do not bear fruit, short fruit branches leave 1 fruit every 2 ~ 3 branches, middle fruit branches leave 1 ~ 2 fruits, and long fruit branches leave 2 ~ 3 fruits; Generally, each fruit tree has 380 ~ 460 trees. ?

5. Bagging?

It should be done immediately after the fruit setting of Jinxiu yellow peach (42 ~ 49 d after flowering), and bagged before the peach moth lays eggs in Jinxiu yellow peach garden damaged by peach moth. Before bagging, apply 1 fold pesticide scientifically and reasonably to control scab, brown rot and other diseases, and apply 1 fold pesticide to control aphids, leafhoppers and other pests, and the concentration of the pesticide should not be too high. No bagging garden 10 ~ 14~20 d spray 1 time, bagging garden 14~20 d spray/time.

However, it should be noted that the second generation moth eggs must be sprayed with pesticides 1 time on May 4-8, and then mixed with fungicides to treat other diseases. Spraying must be meticulous and thoughtful, and it is advisable to wet the branches and leaves up and down without running water, and spray the fruit bag to avoid germs invading the fruit bag. ?

6. Strengthen the management of parks?

Actively introduce and cultivate excellent varieties that are healthy and free from pests and diseases, strengthen the management of water and fertilizer in the park, scientifically apply organic fertilizers and phosphorus and potassium fertilizers, clean up fallen leaves, weeds and fruit drops in time during the dormancy period of fruit trees, prune dead branches, old branches and insect branches of fruit trees, focus on burning, eliminate the source of pests and diseases, and improve the ventilation and lighting conditions in the park.

Chemical agents can also be sprayed to reduce the source of the disease, such as spraying with 5 shellfish stone sulfur mixture 1 ~ 2 times. When pruning in winter, removing branches of diseases and pests can effectively reduce the source of disease.

The combination of cleaning in growing season and pruning in summer can effectively prevent and reduce the occurrence and prevalence of gummosis of Jinxiu yellow peach. Hanging insect forecast lights, black lights and sex traps to collect, process and analyze monitoring data, and accurately grasp the dynamics of insect situation. ?

7. Scientific use of chemicals?

Use herbicides, fertilizers, pesticides and other chemicals as little as possible, and prohibit the use of highly toxic and long-term pesticides; Try to use recyclable or degradable containers when raising seedlings; Packaging materials such as packaging bags and pesticide bottles should be recycled; A special person shall be appointed to manage chemicals, and the product name, scope and method of use, quantity and shelf life shall be clearly marked on all chemical labels to ensure the safety of storage and use.

Before chemicals are used, users shall be trained in operation, abide by operating rules, properly handle wastes, and hang obvious signs after use; In pest control, biological agents or pesticides with low toxicity, high efficiency and short residue period should be used as much as possible to reduce the impact on the environment; Try to apply compound organic fertilizer, apply it quantitatively and deeply, and recycle it in fertilizer bags.
