The latest measures to control kiwifruit drop

Kiwifruit, also known as kiwifruit, is a kind of fruit that tastes different from other fruits. It is juicy, sweet and unique. Rich in vitamin C, can stabilize mood, help digestion and other effects. But kiwifruit often fall when growing, how can we effectively prevent and control fruit drop? Come and have a look with the editor.

1. Scientific pollination

It is necessary to finish the pollination work reasonably and change the previous wrong pollination method. Fruit growers should not store pollen for more than a year, because the purity of the pollen collected by themselves is high, the pollen can not be sealed and can not maintain a dry environment, and the temperature can not be controlled below-18 degrees. So try not to store, pollen should not be exposed to the sun above 28 degrees, nor can you use cooking machines and other tools to get powder, because this will further reduce the purity of pollen.

2. Water management

For the moisture in the ground must be kept in a suitable environment, the water content in the ground should be more than 65%; pay attention to the humidity in the field, the humidity in the orchard should be above 55. However, it should be noted that pollen can not meet water, if it meets water, the style of pollen will break, resulting in inability to pollinate, which is counterproductive.

3. Deal with bad weather

When the low temperature comes, some chemicals such as cloth amino acid should be sprayed to improve the resistance of fruit trees. If irrigation can delay the flowering time of kiwifruit during flowering and let the flowers avoid the low temperature climate, the loss will be reduced. If it is to come to the frost season, it is necessary to take artificial smoke control to protect trees from freezing; if it is after flowering, it depends on the situation of pollination. If you encounter high temperature weather, you should irrigate a lot of water, but you should irrigate too much water at one time to prevent falling flowers due to the large temperature drop.

4. Strengthen the management

To improve the fertility of the soil, about 3000 kilograms of farm manure is used as the base fertilizer and fertilized evenly. Remove weeds in the orchard, enhance the facilities in the orchard, automatic fertilization and watering and other integrated equipment. And to properly trim long branches, adjust the nutrition and development of trees, planting density can not be too dense, the yield per mu is about 1000-2000 kg.

5. Prevention and control of diseases

The disease-resistant seeds should be selected when selecting seeds, or the seeds should be disinfected before sowing to improve the disease resistance of the whole plant. When you find the characteristics of the disease, you should spray in time, clean up the disease and disinfect the orchard. Before and after Ching Ming Festival is the onset period of Sclerotinia sclerotiorum disease, which can be prevented by spraying ethylene sclerotiorum and other agents. But do not do it when the temperature is high, to avoid drug damage.

The above are the pre-control measures of kiwifruit drop. Kiwifruit is a kind of fruit which is very sensitive to the external environment. It must be important at the stage of flowering and fruiting. If you want to know what causes kiwifruit drop, you can follow the pro-agriculture network to check the previous articles!
