Latest Apple Management Techniques and Methods Tutorial for May
Apple is a very common fruit and is grown on a fairly large area in China. Growing apples has also become a way for many people to make a living. As May approaches, apple management becomes increasingly important. Good management is the key to ensuring apple yield. So how should you manage them in May? Below, the editor brings you the key points of apple management techniques for May. Let's take a look!
1. Spray foliar fertilizer
Apple trees have a very high demand for fertilizers such as calcium and boron. About one month after the apple trees bloom, their demand for calcium rises sharply. Reasonable calcium supplementation can meet the apple's demand for calcium. It can also enhance the quality and firmness of the fruit and reduce the incidence of pests and diseases. It prevents undesirable conditions such as water cracks and dehydration. Therefore, after flowering, we must pay attention to calcium supplementation. Then, at full bloom, pay attention to spraying boron fertilizer. This promotes pollen germination, increases fruit set, strengthens disease resistance, and improves growing returns.
2. Flower and fruit thinning
The purpose of flower and fruit thinning is to prevent the number of flowers and fruits from exceeding what the apple tree can bear. It reduces nutrient consumption, improves the fruit set rate of the apple tree, and prevents undesirable conditions such as alternate bearing. It can begin after the apple tree enters the bud stage, keeping one flower cluster about every 20 cm on each branch. Then, after the flower clusters set fruit, thin out side fruits, small fruits and all kinds of deformed fruits, concentrating nutrients on the vigorous fruits. For trees that have not yet been pollinated, pollination must be carried out first. Then flower and fruit thinning should be carried out according to the actual situation.
3. Reasonable watering
In spring, in order to advance the growth time of spring shoots, pay attention to watering the orchard about 7 days after flowering. Because flowering and fruiting consume too much water from the apple tree, water must be replenished in time. Then, after entering May, watering should be stopped to promote the growth of spring shoots. In June, the apple tree gradually begins flower bud differentiation, and at this time the amount of watering should be controlled as much as possible. So if you want to water again after April, it is generally done in summer. Therefore, everyone should water enough in April to ensure that the water needs of the following two months are met, enhance the growth of spring shoots, and improve the flowering and fruiting rate.
4. Pest and disease control
May is roughly also the flowering period of apple trees, and this is also the time when pests and diseases do the greatest harm. So we should, according to the specific flowering time of the apple trees, pay attention to spraying fungicides and insecticides about 4 days before flowering. This suppresses the growth of pathogens. Spraying at this time is very important and must be thorough and complete. Then, after flowering and before bagging, attention should also be paid to spraying pesticides to prevent fruit diseases, avoid damage to young fruits, and prevent a decline in yield. Observe the growth situation frequently, and when abnormalities are found, promptly check the cause and then take corresponding measures.
The above is a brief introduction to the key points of apple management techniques for May. The management of apple trees is very important, especially during the spring flowering period. Poor management will seriously reduce the flowering rate of apple trees, leading to a decline in yield and lower growing returns. That is all for today's introduction.
