Crops-fertilizing method

Abstract

The invention discloses a crops-fertilizing method, which comprises the following: (1) a step of calculating the soil productivity according to the type of to-be-fertilized land through a formula which is first-season soil productivity plus second-season soil productivity equals soil productivity, (2) a step of formulating a pre-production plan, determining target yield and determining fertilization amount according to fertility needed by the target yield, wherein calculation formulas of fertilization amount are: the total amount of chemical fertilizer needed by the target yield minus soil productivity equals fertilization amount, and target yield which is divided by 100 and then multiplied by absorption amount per 50 kg is the total amount of chemical fertilizer needed by the target yield; and (3) a step of fertilizing, which is to fertilize the land according to the fertilization amount figured out. The fertilizing method does not need to measure soil, formulates the pre-production plan according to the own growing environment of crops and the growth characteristics of the crops, calculates the soil productivity, formulates a fertilizing plan, and then performs fertilization, thereby having the advantages of high benefit, low input, high output and the like and corresponding with the demand of farmers, and popularization and application are suggested.

Description

technical field [0001] The invention relates to a method for fertilizing crops. Background technique [0002] At present, the Chinese people have more land and less land, and the task of achieving self-sufficiency and satisfying food and drink is arduous. One of the important reasons is that the fertilization technology is backward and blindly fertilizing, resulting in low efficiency and poor quality of crops, and it is not possible to make full use of and tap land resources. , affecting the rapid improvement of living standards and the rapid development of national strength. [0003] At present, there is a common phenomenon in the fertilization of crops: "Fertilizers follow one, not according to one's own soil strength, random evaluation after harvest, and true and false fertilizers", which is specifically manifested as follows: whichever farmer has a high crop yield, it is followed by the corresponding variety name , fertilization methods run; most farmers listen to the e...

Problems solved by technology

[0002] At present, the Chinese people have a lot of land and little land, and the task of achieving self-sufficiency and satisfying food and drink is heavy. One of the important reasons is that the fertilization technology is outdated and blindly fertilizing, resulting in low crop efficiency and poor quality, let alone the inability to fully utilize and tap land resources. , affecting the rapid improvement of living standards and the rapid development of national strength

[0003] At present, there is a common phenomenon in the fertilization of crops: "Fertilizers are followed by one, not according to their own soil strength, randomly evaluated after harvest, and the fertilizers are true and false". , fertilization methods; most farmers listen to the explanations of chemical fertilizer dealers, and they cannot judge by themselves, let alone apply scientifically; and because of the variety of chemical fertilizers, the quality is different, which greatly reduces the enthusiasm of farmers to farm efficiently.
