Management of fruit bearing period of pitaya

Dragon fruit is the fruit of cactus family, the plant shape is very similar to the shape of cactus, easy to cut and survive. Therefore, it is relatively easy to grow and manage, and it can be adapted to planting in many parts of the world. For the management of dragon fruit, probably the focus of management can be placed on the fruit period management, after all, fruit yield, quality is the most important. The following work should be done carefully during the result period.

1. Temperature

The dragon fruit is a tropical fruit, so the temperature required for the whole growth period is relatively high, and low temperature is not suitable for its growth. But the temperature above 38 degrees or the low temperature below 10 degrees will affect the growth, may stop the growth, and can not blossom and bear fruit. The best growth temperature is between 25 and 35 degrees. It is best to plant in areas where the annual temperature is above 20 degrees.

two。 Fertilizer and water

The pitaya root system is weak, the whisker root system is widely distributed, and the root system has poor tolerance to water, so it can only be kept moist. But can not accumulate water, a day of stagnant water, most of the roots will die, in serious cases, the plant will die. The dragon fruit is more drought-tolerant, but in order to survive in the normal water supply, a dragon fruit needs to absorb about one jin of water in three days to maintain its life. High temperature moisture must be sufficient to avoid rapid growth without moisture and fruit cracking. Observation of branch flattening usually needs to be replenished with nutrient solution. One fruit branch leaves a high-quality flower, and fertilizer is supplied centrally.

3. Disease prevention and cure

The prevention and control of canker mainly harms the stem and fruit. High temperature and heavy rain is the cause of complication, and the disease is prevalent. Use methyl thiophanate, carbendazim, mancozeb and other broad-spectrum fungicides with copper preparation spray, or use (Kuifuling) solution to smear, cut off diseased stems and fruits and burn them. Anthracnose mainly infects late fruits and is also prevalent in high-temperature and humid environments. Close planting and excessive nitrogen fertilizer are the inducement. There are mainly water-immersed sunken brown spots, using broad-spectrum fungicide Liangguoan 300 times liquid + Wofengsu foliar fertilizer 25ml to spray 30 jin of water.

4. Bagging picking

When the fruit is slightly softened after ripening and changing color, you can put on a paper bag to prevent agricultural operation machinery injury, or birds and insects gnawing injury. When bagging in cloudy and dry days, there should be no moisture on the bagged surface of the fruit. About 20 days after bagging, it is basically mature and can be picked together with the bag as soon as possible.

The fruit period management of dragon fruit should not only pay attention to the good management in other periods, but also carry out special management according to the characteristics of the result period. Then it is to refine the content and do well all the details of the work to be managed. In this way, the piping task is completed.
