Method for storing fertilizer and water in holes by film coverage

Abstract

The invention discloses a method for storing fertilizer and water in holes by film coverage, belonging to the technical field of fertilization. The method for storing the fertilizer and the water in the holes by film coverage comprises the following steps specifically: building ridges, ditching, digging the holes, putting straw bundles in the holes, applying fertilizer to the holes and irrigating the holes, covering the holes by plastic films; pressing the edges of the plastic films tightly by soil, digging a hole with a diameter of 10 cm in the center of each hole by a thin film hole puncher, inserting a rain-collecting fertilizer applicator in the center of each hole along the center of the hole of the plastic film until the upper edge of the rain-collecting fertilizer applicator is inserted in the hole. By adoption of the method for storing the fertilizer and the water in the holes by film coverage, rain and snow are sent to the effective parts of fruit tree roots with well developed root systems for absorbing water by the rain-collecting fertilizer applicators so as to meet needs of the fruit trees; therefore, the non-available water is changed into effective water; meanwhile, by film coverage, the low temperature is improved and the soil moisture evaporation is reduced; the fruit garden can save water by more than 70%; the manpower and material resources investment is reduced; the method has an effect of saving resources and cost.

Description

technical field [0001] The invention belongs to the technical field of fertilization, in particular to a method for storing fertilizer water in film-covered holes. Background technique [0002] Walnuts are Juglandaceae plants, and walnut kernels are rich in nutrients, including 15-20 grams of protein, 60-70 grams of fat, and 10 grams of carbohydrates per 100 grams; Minerals, and vitamins such as carotene and riboflavin. It is beneficial to the human body and can strengthen the brain. It is one of the nut foods loved by the common people. [0003] At present, in the dry-farming fruit tree cultivation areas in northern my country, the traditional methods of fertilization in ditches and holes, flood irrigation or ditch irrigation are mainly used. The technology of storing fertilizer and water in holes has also been applied in individual orchards. The main method is to cover small squares of plastic. The film, the small flow hole method. These methods mainly have the followin...

AI Technical Summary

Problems solved by technology

These methods mainly have the following problems. The first is that the implementation process is complicated and the labor intensity is high. The second is that the secondary fertilization is difficult and there are many repeated procedures. The third is that the film mulching affects the weeding of the orchard. Sixth, the utilization rate of invalid rainfall and snowfall is low. Seventh, the water retention capacity of orchards is low. Eighth, the soil is easy to compact and has poor air permeability. Ninth, the growth period of trees is relatively long.
