How to manage the cultivation of nuclear-free yellow skin?
First, the pruning of the non-nuclear yellow skin, the result of the cultivation:
In the fifth year after the seedless yellow skin planting, it began to enter the adult result tree. After harvesting the fruit, focus on shortening the cut-off result branches, clearing the weeds in the garden, and focusing on cutting off the dead branches, diseased branches, and Yin branches to ensure ventilation and light transmission. It is an important technical link to promote high yield and stable production in the coming year.
1. Fertilization. Organic fertilizers such as human waste and urine are combined with nitrogen, phosphorus and potassium fertilizers for secondary application. For the first time, the autumn shoot fertilizer is applied 10 to 15 days before and after fruit picking. The second time is to apply the strong fertilizer before the end of September. Before the end of October, the leaves will turn green and mature, and the leaves can be sprayed 2~3 times in the green period. Foliar fertilizer, promote the autumn shoots fully mature.
2. After irrigation and fertilization, the orchard is filled with water around the canopy to keep the soil moist and timely send out the autumn shoots.
3, pest control, in the autumn shoot leaves turn green, strengthen pest control, combined with foliar fertilizer spray, to control red spiders, leaf miner, anthracnose and other pests.
Second, promote the differentiation of flower-free yellow skin flower buds:
In the middle of December, according to the weather conditions, adjust the fertilizer and water, protect the autumn shoots, control the winter shoots.
Methods: (1) Drainage of the ditch, loose roots or ring cutting. (2) Use 500-800ppm longer or paclobutrazol, even spray 2 times, once every 15 days. Both have the effect of inhibiting vegetative growth, promoting flower bud differentiation, and shortening the length of flower spikes.
Third, the ribs and strong flowers of the nuclear-free yellow skin:
The buds are stretched when combined with shortening the length of the spikes.
Methods: (1) cut off the whole flower spike on the weak branch; (2) the large spikes of the large flower spikes, the dense spikes, the long short spikes, the medium-sized spikes, and the 0.2% phosphoric acid at the flower bud stage. Potassium hydrogen plus 0.1% borax, sprayed two times after half a month. Measures: Strengthen fertilization, apply flower fertilizer before and after the Great Cold, and combine with slow-acting fertilizer and quick-acting fertilizer.
Fourth, the non-nuclear yellow skin of the flowers and preserved fruit:
The fundamental measure for preserving flowers and fruits is to strengthen the management of fertilizer and water throughout the cultivation process, enhance the tree potential, and strengthen the flowers and preserve the fruit.
Methods: (1) Short-cutting spikes; (2) Spraying the drug, spraying 5ppm of 2.4D plus 50ppm920 during the full bloom period. Measures: Apply 15~20 days after the second flowering period to cultivate the fruit fertilizer, with potassium and nitrogen fertilizers, and phosphorus and magnesium fertilizers.
5. Non-nuclear yellow peeling fruit and anti-split fruit:
The amount of fruit retained in the whole tree should be determined according to the age of the tree, the tree potential, the size of the canopy, the number of branches and leaves, etc., so that the color of the leaves after harvesting is not green, and the number of healthy fruit branches can be extracted in time.
Method: After the first young fruit (soybean size) is stable, the fruit can be thinned. Firstly, the fruit with unreserved value such as cracked fruit, rotten fruit, diseased fruit, etc. is removed, and the small fruit is removed again. Drain the dense fruit and individual extra large fruits, so that the whole ear fruit is evenly distributed and the size is the same, and the fruit per ear is 20-40.
In the middle and late stages of the development of the seedless yellow skin, special attention is paid to the problem of cracking: (1) regulating the water in the garden; and (2) adding fertilizers such as boron, sulfur and calcium.
6. Ripening and harvesting of non-nuclear yellow skin fruit:
The seedless yellow-skin fruit is characterized by sharp edges and leaves before immature, and the fruit top has a square angle. From the end of June to the beginning of July, the fruit rapidly expands and enriches, the edges disappear, and the fruit turns yellow. The seedless yellow skin is not the same as the fruit of the local yellow skin. When the non-nuclear yellow skin is turned from orange to brown, it will truly show the non-nuclear yellow skin flavor.
Measures: (1) Folks generally use sprayed decomposed green urine; (2) Spraying fertilizers with two elements such as K and S can enhance fruit ripeness and rich flavor.
