High-yield fertilizing method for fruit trees

Abstract

The invention relates to a fertilizing method in the field of agriculture, in particular to a high-yield fertilizing method for fruit trees. The high-yield fertilizing method for the fruit trees comprises the steps: (1) fertilizing in spring; (2) fertilizing in a flower bud period of the fruit trees; (3) applying leaf fertilizer in a flowering period, and applying water-soluble fertilizer to the roots in a flushing way at the same time; (4) spraying manntiol calcium on leaf surfaces in a full-blossom period and a young fruit period; (5) applying leaf fertilizer in a fruit inflating period; (6) performing topdressing and applying water-soluble fertilizer to the roots of the fruit trees in a fruit swelling period; (7) applying organic fertilizer to the roots of the fruit trees in autumn after fruits are harvested; (8) applying microbial agent to the roots of the fruit trees. According to the high-yield fertilizing method for the fruit trees disclosed by the invention, different fertilizer is applied in different periods of the fruit trees, and the fertilizing method is more beneficial to leaf growing, flowering and fruiting of the fruit trees. The fertilizing method disclosed by the invention is suitable for varieties of fruit trees, has a wide application range and avoids the problems of root burning, fruit abscission, fruit reduction and the like in application. Furthermore, the fertilizing method is simple to operate, can improve growth rate of the fruit trees and has important application value.

Description

[0001] (1) Technical field [0002] The invention relates to a fertilization method in the agricultural field, in particular to a high-yield fertilization method for fruit trees. [0003] (2) Background technology [0004] During the growth of crops, they need to absorb various mineral nutrients from the soil in order to maintain their normal growth and development and complete their life course. Among them, it includes a large number of elements such as nitrogen, phosphorus, and potassium, medium elements such as calcium, magnesium, and sulfur, and trace elements such as iron, manganese, copper, zinc, molybdenum, and boron. In the modern agricultural production system, since the cultivated soil can provide limited mineral nutrients for crops to absorb during the crop growing season, providing appropriate amount of mineral nutrients to crops through fertilization is one of the fundamental measures to ensure the yield and quality of crops. [0005] After the fertilizer is appli...

Problems solved by technology

However, in such a fertilization method, the following disadvantages will occur: ①The nutrient concentration in the soil solution is very uneven, and there will be a local high concentration in a short period of time after fertilization, which may even cause seedling burning; In a long period of time, the fertilizer concentration may be far lower than the appropriate concentration required by the crop; ②The fertilizer is fully mixed with the soil, and the contact surface is large: by spreading the fertilizer on the soil, but because the crop root system only exists in a certain area of ​​​​the soil , and there is no crop root system in other areas of the soil, the fertilizer in this area cannot be directly absorbed by the plant root system, resulting in a waste of fertilizer; and if local fertilization is used, due to the dynamic growth of the crop root system, it is difficult to make the fertilization area and The root area of ​​the crop is highly consistent; ③Once the fertilizer is applied to the soil, it will turn around according to its inherent natural law, and the behavior of the fertilizer in the soil cannot be controlled

Especially after the crops are harvested, the remaining fertilizer nutrients that have not been absorbed and utilized by the crops are basically wasted; ④ It is difficult to highly match the nutrient demand of the crops with the supply of fertilizer nutrients, thus affecting the efficient absorption and utilization of fertilizers by the crops; ⑤ If large Rainfall or excessive irrigation can lead to loss of fertilizer nutrients due to excessive soil moisture content
