The latest course of Scientific Orchard Management techniques of Yellow Peach

Yellow peach has always been an excellent peach variety in China, which has succulent juice, delicious taste, immunity and other functions, is a health fruit, generally listed in August. Its planting efficiency is high, and at present, the planting area is also expanding, but there will inevitably be a variety of problems in the planting process. Let's take a look at the orchard management technology of yellow peach with Xiaobian.

1. Fertilizer and water regulation

If the yield of yellow peach is to be high, it is necessary to apply fertilizer. Its principle of fertilization is to apply thin fertilizer frequently, promote before and control after. Generally, it should be fertilized three times before June, and each plant should apply about 50 grams of urea and 50 grams of potassium dihydrogen phosphate. Yellow peach is suitable for acidic soil, so ammonium bicarbonate can not be applied when fertilizing, it will alkalize the soil, the growing period should be easy to lack magnesium, iron and other elements, should be replenished in time. The amount of fertilizer needed in the fruit stage is the most, accounting for about 40% of the total amount of fertilizer applied in the whole year.

2. Pruning and shaping

Yellow peach has strong germination and branching ability, so it is necessary to prune branches and leaves frequently during the growing period, so as not to affect permeability and be disadvantageous to plant growth and development, mainly pruning overgrown and overdense shoots, unretained new shoots, weak shoots, superfluous shoots, and late autumn shoots that consume nutrition. The pruning of young trees is mainly stereotyped. In addition to the trunk, it is necessary to retain enough lateral branches, retain branches step by step, and remove excess branches to promote young trees to form a crown as soon as possible. With vigorous growth in summer, fruiting trees can change shoots, cut off some old branches and leave some new shoots, and some growing lateral branches are too dense, which can be removed by hanging, opening angle, basal buds and redundant buds. Winter repair is mainly to clean up dead branches, disease and insect branches, improve structure, renew and rejuvenate, and so on.

3. Fruit period management

There are three physiological falls in the fruit period of yellow peach, so it is necessary to wipe buds to promote strong branches, and then to fertilize and protect nutrition, remove some branches, and concentrate on nutrition supply to the fruit. Timely thinning fruit, retain good nodes on strong branches of high-quality fruit, at the same time to remove diseased fruit, stiff fruit, small fruit, abnormal fruit, cluster fruit to retain one or two good fruit, other removal. The fruit can be protected by spraying growth regulator and bagging after spraying fungicide to protect the fruit from diseases and insect pests.

4. strengthen the prevention and control of diseases and insect pests

The main disease of yellow peach is peach anthracnose, which mainly harms the fruit, which will form disease spot and finally rot and fall off, which will seriously affect the yield and quality of yellow peach. In addition to timely pruning diseased fruit and diseased branches, it is also necessary to spray 5 Baumetu stone sulfur mixture mixed with 100 times pentachlorophenol sodium before germination to eliminate overwintering bacteria. The cub was sprayed with 80% anthrax 800 times solution or 72% DuPont Krou 800 times solution during the onset of the disease. The main pest is peach aphid, which can prick and suck juice to cause coal fouling disease and spread viral diseases, which can be prevented by spraying 1000 times solution of 40% dimethoate EC or 1000 times solution of 40% acephate EC.
