The Latest Cultivation Techniques for Increasing Yellow Peach Yield
The yellow peach is a fruit with very high nutritional value, but its current yield is not particularly good, either because it does not bear much fruit or because the quality is poor. Many methods have been tried, and although there has been some improvement, the effect is not obvious. So what exactly should be done to increase the yield of yellow peaches? Today Qinnong Web will teach everyone how to increase the yield of yellow peaches.
1. Select good varieties
Because the yellow peach has strong resistance, it can be planted anywhere, but when it comes time to bear fruit, you will find that the yield of yellow peaches planted in some places is not very good. What is the reason for this? It is because the yellow peach variety you planted is not particularly suitable for growing there. There are now very many types of yellow peaches, such as Jiashan yellow peach, Dalian yellow peach, Guangming yellow peach, and so on. Some of them have stronger cold resistance, some have stronger disease resistance, and others have strong drought resistance or waterlogging resistance. Therefore, when planting, you need to investigate the local climate and then choose the most suitable variety, so as to solve the problem of yellow peach yield at the root.
2. Improve fertilizer use
Improving fertilizer use includes two aspects: the first is the type of fertilizer, and the second is the method of fertilization. First, let us look at the types of fertilizer. Generally, farmyard manure is the main type, followed by urea to promote growth, then boron fertilizer and potassium fertilizer to protect the fruit, and finally some phosphorus fertilizer, compound fertilizer, and nitrogen fertilizer as supplements. Fertilization methods are divided into three stages: during the seedling stage, urea is favored; for adult fruit trees, phosphorus fertilizer is favored; for aging fruit trees, potassium fertilizer is favored. Fertilization of adult fruit trees is the most critical. It is divided into three steps. The first is the leaf expansion stage, when urea and compound fertilizer or farmyard manure are used for irrigation. The second is the flowering stage, when potassium fertilizer and boron fertilizer are sprayed to promote flowering and protect fruit, and to increase the fruit-setting rate. The third is after harvest, when farmyard manure is piled on to prepare for a high yield the following year.
3. Prevent fruit drop
The yellow peach has a very obvious characteristic: its flower-setting rate is high, but its fruit-setting rate is not high, because its fruit drop phenomenon is very serious. So how should fruit drop be prevented and controlled? The first fruit drop occurs when the fruit sets after the flowers fall. The control method at this time is to carry out flower and fruit thinning on your own, which can avoid the shedding of vigorously growing fruit and ensure fruit quality. The second fruit drop occurs when the yellow peaches are about to mature. We mainly need to pay attention to the management of nutrients and water in the field. Nutrients should not be excessive, especially nitrogen fertilizer, which must not be applied. There is also an external factor, which is that pests cause fruit to drop, so pest control is necessary.
4. Pruning branches and leaves
Yellow peaches have relatively strict requirements for light. If the soil fertility is relatively sufficient and the external environment is relatively stable, then the yellow peach tree will grow very luxuriantly, so that the ventilation and light transmission in the yellow peach orchard are not very good. Then we need to cut away part of the branches and leaves that are growing too luxuriantly and retain the strong branches. Next, cut off all drooping branches and leaves, branches and leaves infected by disease, and aging branches and leaves, so as to ensure sufficient light and achieve a reasonable growth density.
5. Bagging technique
Bagging technique is a relatively new method of fruit protection now. In fact, bagging does not necessarily mean that a bag must be put on the peach to be called bagging. It means that during the growth period of the yellow peach, a newly developed high-fat film is applied to the surface of its fruit, or a protective agent for mist poisoning is sprayed on the surface of the fruit. This is equivalent to putting a bag around the fruit, which can protect the yellow peach from dropping and from disease invasion, achieving the effect of increasing yield.
