specific Embodiment approach 1

[0010] Specific embodiment one: a kind of method for fertilizing rice in cold regions, the method for fertilizing rice in cold regions divides fertilization into four times, specifically completes according to the following steps:

[0011] 1. Application of base fertilizer: plow the plot in autumn, apply 3 kg / mu of base fertilizer urea, 6 kg / mu of diammonium phosphate and 4 kg / mu of potassium chloride into the field before soaking the field, then rotate the ground, mix the fertilizer and soil, and Irrigate shallow water for land preparation; turn over the plot in spring, apply 3 kg / mu of base fertilizer urea, 6 kg / mu of diammonium phosphate, and 4 kg / mu of potassium chloride into the field before turning the land, then spin the field, mix the fertilizer and soil, Shallow water land preparation;

[0012] 2. Turning green fertilizer: 1-2 days before transplanting or on the day of transplanting, apply turning green fertilizer in the field. The amount of turning green fertilizer i...

specific Embodiment approach 2

[0020] Specific embodiment two: the difference between this embodiment and specific embodiment one is: in step 3, tiller fertilizer is applied to Honda 10 days after transplanting. Others are the same as the first embodiment.

specific Embodiment approach 3

[0021] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is: the tillering fertilizer described in step 3 is mixed with herbicide. Others are the same as those in Embodiment 1 or 2.

[0022] The content of the present invention is not limited to the content of the above-mentioned embodiments, and a combination of one or several specific embodiments can also achieve the purpose of the invention.

[0023] Adopt following test verification effect of the present invention

[0024] Select two adjacent grounds in a certain place as the test field, the test field 1 is planted according to the fertilization method of the present invention, and the test field 2 is planted according to the prior art, and the specific operations are as follows:

Abstract

The invention belongs to the technical field of agricultural crop planting, in particular to a fertilizing method for rice in a cold region. The invention aims at solving the problems that existing fertilizing of the rice in the cold region is unreasonable, the fertilizing amount is large, the use ratio is low, the planting cost is increased, and land salinization is caused. According to the fertilizing method for the rice in the cold region, fertilizing is conducted four times, that is, base fertilizer, striking root fertilizer, tillering fertilizer and earing fertilizer are conducted sequentially. The fertilizing method for the rice in the cold region has the advantages that the time and dosage of fertilizing are strictly controlled, the input of fertilizer auxiliary materials is reduced, the applying amount of the fertilizer is reduced, the labor amount for fertilizing is reduced, and the production cost is reduced; the fertilizing method is simple and effective and can well increase the yield of the rice. The fertilizing method for the rice in the cold region is mainly used for fertilizing of the rice in the cold region.

Description

technical field [0001] The invention belongs to the technical field of agricultural crop planting, and in particular relates to a rice fertilization method. Background technique [0002] More than half of the world's population eats rice, and it is one of the main food crops in my country. Rice production is related to the national economy of our country. In the process of rice planting, the quality of fertilization is closely related to the yield of rice. In order to increase the yield, the amount of fertilization is usually increased blindly. Although excessive fertilization will increase the yield of rice to a certain extent, it will also bring a serious burden to the land, and will cause land salinization at the same time. Increased planting costs to a certain extent. Therefore, in order to adapt to the amount of fertilizer applied by farmers, some fertilizer manufacturers add a large amount of low-content auxiliary materials to the fertilizer to increase the amount o...
