First, avoid applying chlorine fertilizer
Peach trees are chlorine crops that are sensitive to chloride ions. The use of chlorine-containing fertilizers such as potassium chloride, etc., will cause the roots of peach trees to rot, and the leaves will turn yellow, and the weak ones will be debilitated and the entire ones will die.
Second, avoid spraying dimethoate
Peach is sensitive to dimethoate and omethoate, and it easily causes scorch and shedding of leaves after spraying.
Third, bogey watering
Peach is a fruit tree that is afraid of pods. After irrigating, the air content in the soil is low, and the root system undergoes anaerobic respiration. The absorption function is reduced, resulting in malnutrition up and down the tree, causing the peach trees to fall and fall.
Fourth, avoid warming prematurely
The premise of warming is that the peach trees in the greenhouse need enough cooling. Therefore, it is necessary to determine the required cooling capacity of the main cultivar before heating.
Fifth, avoid excessive temperature
Peach trees in greenhouses should not be too rushed when they start to warm up; the temperature is controlled below 18°C ​​and does not exceed 25°C before flowering; the flowering period should be controlled below 22.5°C, and the maximum should not exceed 25°C; the temperature after fruit setting should not exceed 28°C. If the greenhouse temperature is too high during the flowering period and flowering period, it will result in irregular flowering and low fruit setting rate. If the temperature of the fruit is too high during the fruit development period, it will cause leggy and fruit drop.
Six, bogey mulch
Indoor sheds do not cover the mulch, which will cause high temperature in the shed, low ground temperature, slow root activity of the peach tree, uncoordinated growth of the tree, affecting fruit set and fruit growth.
Seven, avoid a single species
Compared with cross-pollination, self-pollination results in low fruit setting rate, poor fruit quality, and small fruit size. Therefore, varieties with the same flowering period, large amount of pollen and good quality should be allocated as pollination varieties.
Eight, avoid pollination method single
Peach trees are generally younger in the greenhouse and have fewer flowers than peaches planted in the open air. In the shed, the air flow is small, the relative humidity of the air is large, the anther cracking is slow, and pollen viscosity is not easy to pollinate. A variety of pollination methods should be adopted to increase the female flowering rate.
Nine, avoid too much fruit
The density of the peach trees in the greenhouse is large, the space is small, and there are many leaves. If there are many fruits left and the tree body is overburdened, it will cause the phenomenon of the size of the fruit trees, and the fruit color will be small; if the fruit is left, the yield will be low. Should be according to the tree, tree potential appropriate fruit.
Ten, bogey before picking water
Pre-harvesting water can easily cause cracking, especially nectarines. It can also cause poor fruit coloration, low sugar content, delayed maturity, and impatience for storage and transportation.
