1. Do not apply chlorine fertilizer. Peach is a bogey crop that is 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.

2. Flowering should not be watered. Peach is a fruit tree that is afraid of pods. After watering at the flowering stage, the air content in the soil is low. The root system will undergo anaerobic respiration and the absorption function will decline. This can easily cause up and down malnutrition of the tree, causing the peach trees to fall and fall.

3. It is not too early to warm up. The prerequisite for warming is that the required cooling capacity of the peach tree in the greenhouse is sufficient. Therefore, it should be determined that the required cooling capacity of the main cultivar can be increased.

4. Shelter temperature should not be too high. Peach trees in the greenhouse should not be too rushed when the temperature begins to rise. The temperature should be controlled below 18°C ​​and not exceed 25°C before flowering. The flowering period should be controlled below 22°C and the maximum should not exceed 25°C. The fruit temperature should not exceed 28°C. If the greenhouse temperature is too high during the flowering period and flowering period, flowering will be irregular and the fruit set-up rate will be low. If the greenhouse temperature is too high during the fruit development period, it will lead to new roots and cause fruit drop.

5. The ground cover film. Indoor greenhouses are not covered with plastic film, which will cause high temperature in the greenhouse and low ground temperature. The root activity of the peach trees will be slow and the growth of the tree will not be coordinated, affecting fruit set and fruit growth. At the same time, bare ground can also cause weeds and peach trees compete for water, compete for fertilizer and win light, affecting the growth of peach trees.

6. Configure pollination varieties. Although most of the peach varieties can be self-pollinated, self-pollination and cross-pollination have lower fruits, lower fruit quality, and smaller fruit size. Therefore, the peach trees in the sheds are best equipped with pollen varieties that have basically the same flowering period, large amounts of pollen, and good quality.

7. A variety of ways to pollinate. Peach trees are generally younger in the greenhouse, and the number of flowers is less than that of peach trees cultivated in the open air. In addition, the indoor air flow in the shed is small, the relative humidity of the air is large, the anther cracking is slow, and the pollen viscosity is difficult to pollinate. Therefore, a variety of pollination methods should be used, such as artificial pollination, bee pollination, etc., to increase the female pollination rate.

8. The amount of fruit left in the tree. In greenhouses, peach trees generally have higher density, less space, and more leaves. If too many fruits are left, and the tree is overburdened, it will cause the phenomenon of annual size of fruit trees, and the fruit color will be small. If the fruit is too small, the yield will be low. Should be according to the tree, tree potential appropriate fruit.

9. Do not water before harvesting. Pre-harvesting water can easily cause cracking, especially nectarines, which can also cause poor fruit coloration, low sugar content, delayed maturity, and fruit resistance to storage and transportation.
