The main points of the latest May Apple Management Technology and method course

Apple is a very common fruit, which has a large planting area in our country. Growing apples has also become a planting project for many people to get rich. As we approach May, Apple's management is becoming more and more important. Good management is the key to ensure apple production. So how to manage it in May? The following editor brings you the key points of Apple management technology in May, let's take a look!

1. Spraying foliar fertilizer

Apple has a great demand for fertilizers such as calcium and boron. Demand for calcium rises sharply a month or so after apple trees bloom. Reasonable calcium supplement can meet the calcium demand of apple. It can also enhance the quality and firmness of fruits and reduce the incidence of diseases and insect pests. Prevent the occurrence of water cracks, dehydration and other adverse phenomena. So we must pay attention to do a good job of calcium supplement after flowering. Then pay attention to spraying boron fertilizer in full bloom. Promote pollen germination, increase fruit yield, enhance disease resistance, and improve planting efficiency.

2. Thinning flowers and fruits

The purpose of thinning flowers and fruits is to prevent the amount of flowers and fruits from exceeding the bearing range of apple trees. Reduce the consumption of nutrition, improve the fruit setting rate of apple trees, and prevent the occurrence of bad phenomena such as big and small years. It can begin after the apple tree enters the budding stage, with about one inflorescence on each branch separated by 20cm. Then, when the inflorescence is over, remove the lateral fruit, small fruit and all kinds of abnormal fruit, and concentrate the nutrition on the strong fruit. For trees that have not yet been pollinated, pollination should be carried out first. And then thinning flowers and fruits according to the actual situation.

3. Rational watering

In order to make the spring shoot grow earlier in spring, we should pay attention to watering the orchard about 7 days after flowering. Because blooming and fruiting will consume too much water in the apple tree, it is necessary to replenish the water in time. Then stop watering after entering May to promote the growth of spring shoots. Apple trees gradually differentiate into flower buds in June, so try to control the amount of water you can pour at this time. So if you want to water again after April, it usually takes place in the summer. Therefore, we irrigate enough water in April to ensure to meet the water demand for the next two months, enhance the growth of spring shoots, and improve the rate of flowering and fruiting.

4. Pest control

May is almost the flowering time of apple trees, and this is also the time when diseases and insect pests are most harmful. Therefore, according to the specific flowering time of apple trees, we should pay attention to spraying germicidal insecticides about 4 days before flowering. To inhibit the growth of bacteria, spraying during this period is very important to ensure that it is comprehensive and thorough. Then after flowering and before bagging, we should also pay attention to spraying chemicals to prevent fruit diseases and young fruit damage, resulting in a decline in yield. Often observe the growth situation, when found that there is an abnormal situation, it is necessary to timely check the cause, and then make corresponding measures.

This is a brief introduction to the key points of Apple's management technology in May. The management of apple trees is very important, especially in the spring flowering season, poor management will seriously reduce the flowering rate of apple trees, lead to a decline in yield and reduce planting efficiency.
