Embodiment 1

[0022] A rice cultivation method, carried out according to the following steps:

[0023] (1) Soak the field in shallow water: before plowing the field in summer, irrigate the field to 2-3cm. The paddy field should be plowed early and deep, and the ground should be finely raked. Keep the water layer for 5-7 days until some weed seeds in the plowed land germinate;

[0024] (2) Cultivated land: If the cultivated land is cultivated twice, it needs to be drained for the first time. After the cultivated land is 4-7cm deep, level the field surface and irrigate to 2-3cm, and keep it for 5-7 days. The organic fertilizer with a weight ratio of 20 is 60g / m 2 Apply basal fertilizer, the cultivated land is 5-8cm deep, and the field is leveled for later use, wherein the organic fertilizer is obtained by the following steps:

[0025] Mix according to the weight ratio of livestock manure, oil residue material 1: straw, rice bran material 1: Bacillus subtilis 0.1, then adjust the water to 35%...

Embodiment 2

[0032] In this example, step (2) press 75g / m2 before plowing the land for the second time 2 The weight ratio of applying C / N is the organic fertilizer of 25, and wherein organic fertilizer adopts the following steps to obtain: by livestock manure, oil residue material 1: rice straw, rice bran material 1: Bacillus subtilis 0.1 weight ratio mixes, and then water is adjusted to 37%, then pile up and ferment, and turn the pile 3-4 times during the fermentation; step (5) is on the 5th day after transplanting, press 90g / m 2 Sprinkle rice bran at the dosage, and water to a water depth of 8 cm, and keep for 40 days; the rest of the steps and processes are the same as in Example 1.

Embodiment 3

[0034] In this example, step (2) press 80g / m before plowing the land for the second time 2 The weight ratio of applying C / N is the organic fertilizer of 30, and wherein organic fertilizer adopts the following steps to obtain: by livestock manure, oil residue material 1: rice straw, rice bran material 1: Bacillus subtilis 0.1 weight ratio mixes, and then water is adjusted to 41%, then accumulate and ferment, and turn the pile 3-4 times during the fermentation; step (5) is on the 8th day after transplanting, press 120g / m 2 Sprinkle rice bran at the dosage, and pour water to a water depth of 8 cm, and keep it for 35 days; the rest of the steps and processes are the same as in Example 1.

Abstract

The invention provides a paddy rice cultivation method comprising the steps of (1) shallow water field soaking, (2) plowing, (3) robust seedling transplanting, (4) water usage management, (5) rice bran spreading, (6) late-stage field management, and (7) paddy rice harvesting. With the method, problems of high weeding cost, non-thorough weeding, and high soil damage caused by the use of pesticides can be solved. Also, paddy rice yield can be improved, and the quality of rice grain produced by the paddy rice can be ensured.

Description

technical field [0001] The invention relates to the technical field of rice production, in particular to a high-quality and high-yield cultivation method for rice. Background technique [0002] Rice plays a vital role in the staple food of human beings, and rice is in great demand, so it needs to be grown in large quantities. The annual planting area is 30 million hectares 2 , The rice planting area accounts for about 33% of the arable land area, while the output accounts for 45% of the country's total grain output. Due to my country's vast territory and complex terrain, and rice planting is affected by various factors such as climate conditions, geographical environment, farming system, and economic conditions, the ways of planting rice in different places are quite different, which leads to the slow development of rice production mechanization in my country. According to statistics in 2000, the mechanized sowing area of ​​rice in my country only accounted for 4% of the r...
