Fertilizing method for chestnut tree

Abstract

The invention discloses a fertilizing method for a chestnut tree, belonging to the technical field of chestnut tree planting. The fertilizing method for the chestnut tree comprises the following steps: (1) fertilization before flowering: applying a pre-flowering special fertilizer prepared from a compound fertilizer, dried chicken manure, trichoderma, urea and water; (2) fertilization during a fruit expansion period: applying a solid fertilizer for a fruiting period prepared from a nitrogen-phosphorus-potassium compound fertilizer, a calcium magnesium phosphate fertilizer, silkworm excrement,borax and anhydrous citric acid, and spraying a liquid fertilizer for the fruiting period; and (3) application of a base fertilizer after leaf falling: preparing the base fertilizer by utilizing plantdebris, earthworm cast, superphosphate, borax, quicklime and trifloxystrobin. The method not only can provide sufficient nutrients for the chestnut tree during different periods, enhance the capability of the chestnut tree to absorb the fertilizers, increase the utilization rate of the fertilizers, and improve the yield and quality of chestnuts, but also can improve soil properties of a chestnutorchard, improve the soil permeability, and improve the soil fertility and the capacity of storage and preservation of soil moisture.

Description

Technical field [0001] The present invention relates to the technical field of chestnut tree planting, and specifically to a method of fertilizing chestnut trees. Background technique [0002] Chestnut, also known as chestnut, chestnut, and chestnut, is a plant of the genus Castanea in the Fagaceae family. It grows in areas with an altitude of 370-2800 meters. It is mostly found in mountains and has been widely cultivated artificially. Chestnuts are rich in nutrients, and their vitamin C content is higher than that of tomatoes and more than ten times that of apples. The minerals in chestnuts are also very comprehensive, including potassium, zinc, iron, etc. Although the content is not as high as hazelnuts, it is still much higher than ordinary fruits such as apples, especially the potassium content is three times higher than apples. [0003] With the improvement of people's living standards, the nutritional value and economic value of chestnuts have received more and more a...

Problems solved by technology

Chestnut trees need to be fertilized during the growth process, because there is no suitable nutrient and quantity of fertilizer selected according to the growth needs of each period. After ordinary fertilizer is applied to the cultivated land, part of it will be transpired, dissipated and lost with water, and part will be fixed and used by soil and soil microorganisms. , only a part of it is absorbed and utilized by crops, the role of fertilizers has not been effectively brought into play, and the utilization rate of ordinary fertilizers is very low, resulting in serious waste and decreased soil fertility

Chestnut trees need to absorb more nutrients in a growth cycle, not just nitrogen, phosphorus, and potassium provided by ordinary fertilizers. At present, most chestnut growers arrange the types of fertilizers at will, and the amount of fertilizer is large and single, only focusing on a large number of elements , ignoring trace elements and other nutrients, such fertilization results in abnormal growth of chestnut trees, resulting in thin plants, uneven heading, low pollination rate, and a large number of empty chestnut fruit buds, seriously affecting yield and quality

At the same time, the soil in the chestnut orchard is becoming increasingly hardened, the permeability of the soil becomes poor, it is difficult to coordinate the effects of water, fertilizer, air, and heat, the root system of chestnut trees is underdeveloped, the utilization rate of fertilizers is reduced, and soil-borne diseases are serious. decline, leading to continuous soil erosion in chestnut orchards, decreased soil fertility, and even serious degradation of the soil in chestnut orchards
