The latest course of field management techniques and methods of dragon fruit

The dragon fruit is a kind of tropical fruit, which can be planted all the year round in the tropical climate, but it is better to be planted in spring in our country. The temperature of its growth should be at least higher than 18 degrees, and the highest temperature should not be higher than 40 degrees, otherwise it will be burned. Now dragon fruit is grown in many parts of our country, so today we will mainly learn its field management techniques.

1. Colonization

The planting of dragon fruit is generally based on cutting propagation, so we generally plant according to a reasonable density when cutting, but what we should pay attention to is to check the survival of dragon fruit seedlings in the field and replenish them in time to ensure that the seedlings in the field are neat and finally planted.

2. Fertilizer and water

Fertilization of dragon fruit needs to be carried out strictly according to the principle of frequent application of thin fertilizer, reasonable application of nitrogen, phosphorus and potassium fertilizer, and heavy application of organic fertilizer after dragon fruit planting, and finally, reasonable topdressing of potash and magnesium fertilizer when dragon fruit blossoms and bears fruit, which can make dragon fruit accumulate sugar faster and promote its growth. Throughout the growing period, dragon fruit needs to maintain a certain degree of humidity in the field, the humidity in the air should be at least about 80%, water should be watered every three to four days when the weather is relatively dry, and attention should be paid to drainage when Rain Water is more.

3. Pick the heart

In order to improve the fruit yield of dragon fruit, we need to remove its tip heart when the main branch of dragon fruit grows to about 1.5 meters, which can promote the growth of dragon fruit side branches. to a certain extent, the side branches of dragon fruit need to be the growth of dragon fruit seedlings, otherwise nutrients can not be fully supplied, but also affect the yield of dragon fruit.

4. Weeding

Pitaya is a shallow root plant, so we should be extra careful when weeding, do not hurt the roots of pitaya, when there are few weeds, we can only pull weeds manually, but there are more weeds in the field, and when the planting area is relatively large, we will have a special lawnmower, and then mow the field irregularly, and the cut grass can also be used as fertilizer to promote the growth of pitaya.

5. Pruning

When the dragon fruit is plucked from the heart, it will grow a lot of side branches, so that the plants are relatively dense and can not fully carry out photosynthesis. at the same time, the permeability in the field will also be weakened, which will still affect the yield and quality of dragon fruit. in order to prevent branches from being too dense, we need reasonable pruning of branches and leaves to cut off some old branches, diseased branches and weak branches.

6. Bracket

The paper of dragon fruit cannot bear so much weight, so we need to build some supports around it before the dragon fruit grows to about 1.5 meters or before it begins to blossom and bear fruit, which can support the growth of dragon fruit. The branches of dragon fruit will not be broken. At the same time, it can also ensure the maximum supply of nutrients and calmly increase the yield of dragon fruit.

7. Disease prevention

In general, in the case of good field management, dragon fruit basically will not get sick, but in the seedling stage of dragon fruit, there will still be harm from ants, snails and other insect pests, when we can use pesticides to control. However, if the management is not dealt with properly, then there will be many diseases, such as gray mold, soft rot and so on. The specific situation can refer to the common pest control methods of dragon fruit.
