Problems solved by technology

[0003] Nowadays, due to the large amount of nitrogen fertilizer input and unreasonable application, it not only leads to the continuous decline of marginal yield and nitrogen fertilizer use efficiency, but also seriously threatens the safety of soil and water bodies, bringing about soil acidification, greenhouse gas emissions and groundwater nitrate pollution, etc. become a serious threat to the sustainable development of global intensive agriculture

Embodiment 1

[0028] A rice planting method based on quantitative nitrogen fertilizer application specifically includes the following steps:

[0029] S1 Closing the field for weeding and insecticide: spraying herbicides and pesticides 13-15 days before the rotary tillage of the farmland, the first weeding and insecticide before the rotary tillage of the farmland;

[0030] S2 Farmland one-time plowing: inject water into the farmland, the amount of water injected 0.5-1.5cm above the surface of the farmland, and use the rotary tiller to rotate the watered farmland to ensure intensive cultivation and fine raking, so that the upper layer of the soil is loose and the lower layer is firm, and the farmland Ridge

[0031] S3: Apply base fertilizer: Sprinkle compound nitrogen fertilizer evenly on the farmland after ridging by drone or manually, and the compound nitrogen fertilizer application rate is 40-50kg / hm2;

[0032] S4 Farmland secondary ploughing: the farmland will be trimmed for the second time by th...

Embodiment 2

[0044] As the second embodiment of the present invention, the compound nitrogen fertilizer is composed of 35-40 parts by weight of urea, 25-30 parts of 60% monoammonium phosphate, 30-35 parts of potassium chloride, 10-30 parts of bentonite, and water retaining agent 10-15 parts, ammonium bicarbonate 0.2-2 parts, attapulgite powder 0.2-2 parts, ammonium chloride 21-25 parts, rooting agent 0.1-0.2 parts, swelling agent 0.1-0.3 parts.

[0045] Specifically, the water retaining agent is a starch grafted acrylate copolymer cross-linked product.

[0046] In the rice planting method based on quantitative nitrogen fertilizer application in this embodiment, adding self-made compound nitrogen fertilizer can not only effectively promote the growth and development of crops, but also improve the quality of rice, enhance the cold and drought resistance of plants, and can effectively increase crop yields The quality of its own has better improvement, which can produce growth and rapid growth effe...

Abstract

The invention relates to the technical field of agricultural production, in particular to a rice planting method based on quantitative nitrogen fertilizer application, which is characterized in that quantitative nitrogen fertilizer application is performed before planting and during breeding, and weeding and pest killing are performed before planting and during breeding, so that plant diseases andinsect pests are reduced, high quality and high yield are achieved, and the yield of rice is greatly increased; scientific and reasonable fertilization is carried out on nutrient supply of the rice through the compound fertilizer according to stages, and the method adapts to the whole growth process of the rice; times of cultivation, weeding, pest killing and fertilization are grasped in place, and produced rice is full in grain and rich in nutrition. The self-made composite nitrogen fertilizer is added, so that the growth and development of crops can be effectively promoted, the quality of rice can be improved, the yield of the crops can be effectively increased, the quality of plants is well improved, the growth promoting and rapid growth effects can be achieved, and meanwhile, the invention has the effects of improving the soil environment, strengthening the fertilizer making capacity and improving the yield. The soil microbial metabolism is convenient to promote, and the advantageis stronger.

Description

Technical field [0001] The invention relates to the technical field of agricultural production, in particular to a rice planting method based on quantitative nitrogen fertilizer application. Background technique [0002] Rice is native to China. Rice was grown in the Yangtze River valley in China 7000 years ago. According to different methods, rice can be divided into indica and japonica rice, early rice and mid-late rice, glutinous rice and non-glutinous rice. There are many ways to eat rice, including rice, rice porridge, rice cakes, rice cakes, and rice wine. In addition to being edible, rice can also be used as industrial raw materials for brewing and sugar making. Rice husk and rice straw can be used as feed. The main rice-producing areas in my country are mainly in Northeast China, the Yangtze River Basin, and the Pearl River Basin, which are direct economic crops. [0003] Nowadays, due to the large amount of nitrogen fertilizer and irrational application, not only the ma...
