Cherimoya is rich in pectin and dietary fiber. These substances absorb water, expand through the body, and have a lubricating effect on the intestines. Promotes the metabolism and excretion of food residues in the intestine, prevents and relieves constipation. Cherimoya can also inhibit the body's absorption of heat. Regular consumption can reduce weight and prevent obesity, which will make people's health better and better. Today we will take a look at how to manage the cultivation of soursop!
Fertilizer and water management: The fertilization principle of cherimoya is based on the size of the tree and the different growth stages. Fertilization is generally applied three times a year. The first pruning is in winter, combining deep ploughing and garden cleaning.
Pruning management: Pruning is the key and difficulty of cherimoya cultivation. In general, young trees should adopt the method of picking hearts when they sprout, which can effectively promote the branching of branches, and can cultivate them into a low-growth, multi-branched and even canopy to make the yield more abundant. Keep the trunk about half a meter, and then cut off the leaves in the upper part of the trunk. At this point, the tissue will grow 3 to 4 until it grows to 60 cm, and you can choose the star. On the branches, you can pluck the heart leaves until the third layer of the branches. Pruning after the fruit is also important. Basically once a year. Around March, when the branches start to sprout, you need to cut off all the outer parts of the canopy. Before the third and fourth branches, you can keep two or four branches on the canopy. The rest are dead branches. If there are too many dead branches, they will be cut down. After the branches re-sprouted, only two or three new shoots remained. Remember to pick up the new shoots in time.
Insect pest control of cherimoya! Symptoms of cherimoya leaf spot disease: In the early stage of leaf spot disease, the mesophyll tissue of the anterior and posterior epidermis of cherimoya leaves turns black, forming small black spots. Large black dots form in the later stages. In severe cases, the whole leaf will turn yellow, wilt and fall off.
After pruning, the fungicide should be thoroughly sprayed every year to protect the pruning and reduce the remaining pathogenic bacteria on the diseased leaves. During the growth and development of cherimoya fruit, the two sides of the leaves were sprayed with 50% Benjunling WP 3000 times and 70% zinc propionate WP 400 times respectively to improve the control effect. Try to keep the cherimoya garden well ventilated, cut off the extra long branches and fruitless branches at any time, and reduce the micro-humidity between the fruit trees, thereby reducing the occurrence of the environment.
