Embodiment 1

[0041] A method for one-time fertilization of winter wheat, comprising the steps of:

[0042] (1) In plain wheat production areas where machinery is easy to enter, after the previous crops are harvested, the soil should be plowed deeply or combined with deep loosening and rotary tillage for land preparation;

[0043] (2) The one-time operation of sowing and fertilizing is carried out by the wheat seeding and fertilizing machine, and no topdressing will be carried out in the later stage;

[0044] Select thermoplastic resin-coated controlled-release nitrogen fertilizer. If the nitrogen release period of the product is ≥ 4 months, use 23% (according to pure nitrogen, that is, the nitrogen in urea nitrogen and diammonium phosphate accounts for 23% of the total nitrogen) of quick-acting urea. Use diammonium phosphate as the phosphate fertilizer, and granular potassium chloride as the potassium fertilizer;

[0045] On medium-high fertility soil with a yield of about 500kg / mu, the a...

[0048] A method for one-time fertilization of winter wheat, comprising the steps of:

[0049] (1) In plain wheat production areas where machinery is easy to enter, after the previous crops are harvested, the soil should be plowed deeply or combined with deep loosening and rotary tillage for land preparation;

[0050] (2) The one-time operation of sowing and fertilizing is carried out by the wheat seeding and fertilizing machine, and no topdressing will be carried out in the later stage;

[0051]Select thermosetting resin-coated controlled-release nitrogen fertilizer, nitrogen release period < 4 months, nitrogen initial release rate < 5%, and 15% quick-acting urea (that is, nitrogen in urea nitrogen and monoammonium phosphate accounts for 10% of total nitrogen input) 15%), use monoammonium phosphate as phosphate fertilizer, and use granular potassium chloride as potash fertilizer;

[0052] On high-fertility soil with a yield of about 650kg / mu, the amount of nitrogen fertilizer...

Embodiment 3

[0055] A method for one-time fertilization of winter wheat, comprising the steps of:

[0056] (1) In plain wheat production areas where machinery is easy to enter, after the previous crops are harvested, the soil should be plowed deeply or combined with deep loosening and rotary tillage for land preparation;

[0057] (2) The one-time operation of sowing and fertilizing is carried out by the wheat seeding and fertilizing machine, and no topdressing will be carried out in the later stage;

[0058] The nitrogen fertilizer is biodegradable coated controlled-release nitrogen fertilizer dedicated to winter wheat, the phosphorus fertilizer is heavy superphosphate, and the potassium fertilizer is granular potassium sulfate;

[0059] On medium-high fertility soil with a yield of more than 550kg / mu, the amount of nitrogen fertilizer (calculated as pure N) is 16kg / mu, and the input of phosphorus fertilizer (P 2 o 5 )7.5kg / mu, potassium fertilizer input (K 2 O) 6kg / mu;

Abstract

The invention relates to a winter wheat one-step fertilization method. The method includes 1, in a plain wheat producing area allowing machines to enter easily, after last crops are harvested, performing soil preparation by plowing and subsoiling deeply combined with rotary tilling; 2, allowing a wheat seeder to sow seeds and fertilize by one step, and omitting the post additional fertilization. The nitrogenous fertilizer application is determined according to controlled release nitrogen fertilizer release period, special wheat biodegradable controlled release nitrogen fertilizer is applied or matching with 10% to 20% humic acid urea; or thermosetting / thermal plastic resin coated controlled release nitrogen fertilizer is applied independently or matching with 10% to 30% quick acting urea; phosphate fertilizer is one of phosphate ammonium, diammonium phosphate, calcium superphosphate or triple superphosphate; potassium fertilizer is one of potassium chloride or potassium sulfate. By the one-step fertilization method, fertilizer investment can be saved, the ecological environment can be optimized, labor force is saved, and more benefit can be gained.

Description

technical field [0001] The invention relates to a one-time fertilization method for winter wheat without topdressing, and belongs to the technical field of agricultural fertilization. Background technique [0002] Wheat is the crop with the widest distribution, the largest planting area and the largest trade volume in the world, and its impact on global food security is much higher than that of other crops. Wheat is the second largest grain crop in China after rice. It has been cultivated in my country for more than 5,000 years. The annual planting area is about 355 million mu, and the output is more than 96 billion tons. The output and sowing area account for about 1 / 3 of the world's grain. , the sown area, total output, inventory and consumption all rank first in the world. Wheat accounts for about 43% of China's current total grain consumption, and is the main food for Chinese residents, especially northern residents. Wheat production is directly related to agricultural ...
