Problems solved by technology

In the production of food crops, the labor intensity of rice cultivation is the highest (mainly transplanting and raising seedlings), and with the development of rural economy and the adjustment of industrial structure, a large amount of labor is transferred to the secondary and tertiary industries. Artificial planting has the disadvantages of wasting seedling fields, labor and time, long seedling slowing period, and delayed growth period. Therefore, light cultivation techniques that simplify rice cultivation and reduce labor intensity are receiving more and more attention.

Embodiment 1

[0021] (1) Straw returning to the field: After the rice harvest of the previous season, the straw is crushed to a length of 1-5cm, and evenly sprinkled on the field surface;

[0022] (2) Soil preparation: Irrigate the field surface with 3-5cm of water and soak the field for 2-3 days. The burial depth of straw returning to the field is 12-15cm, and the depth of rotary tillage and land preparation is 10-20cm. Flat, with a height difference of 0-3cm, apply 40kg of long-acting slow-release compound fertilizer within 1-2 days before sowing, and dry and rake the ground again, so that the loose soil layer and the base fertilizer are evenly mixed;

[0023] (3) Rice seed selection: select the rice variety K You 213;

[0024] (4) Rice seed treatment: Soak the rice seeds in water at 18-22°C for 12-18 hours after airing for 2-3 days, then accelerate germination at 30-35°C for 12-24 hours, until the root length is 1cm long and the buds 0.4cm long, mixed with 15ml of 31.9% tebuconazole imi...

Embodiment 2

[0031] (1) Straw returning to the field: After the rice harvest of the previous season, the straw is crushed to a length of 1-5cm, and evenly sprinkled on the field surface;

[0032] (2) Soil preparation: Irrigate the field surface with 3-5cm of water and soak the field for 2-3 days. The burial depth of straw returning to the field is 8-10cm, and the depth of rotary tillage and land preparation is 10-20cm. Flat, with a height difference of 0-3cm, apply 40kg of long-acting slow-release compound fertilizer within 1-2 days before sowing, and dry and rake the ground again, so that the loose soil layer and the base fertilizer are evenly mixed;

[0033] (3) Rice species selection: rice variety K You 213;

[0034] (4) Rice seed treatment: Soak the rice seeds in water at 18-22°C for 12-18 hours after airing for 2-3 days, then accelerate germination at 30-35°C for 12-24 hours, until the root length is 1cm long and the buds 0.4cm long, mixed with 15ml of 31.9% tebuconazole imidacloprid...

experiment example 1

[0041] Select Tianhe rice planting base in Youxian County, 300 mu of test field, be divided into test group 1-3, every group 100 mu, test group 1 adopts embodiment 1 of the present invention, test group 2 adopts embodiment 2 of the present invention, test group 3 adopts embodiment 2 of the present invention For the conventional planting method, K You 213 was selected as rice, and the planting results are shown in Table 1.

Abstract

The invention discloses a rice cultivation method. The method comprises the steps of straw returning to the field, soil preparation, rice seed selection, rice seed treatment, sowing, water management,fertilizer management, disease and pest prevention and control, harvesting and straw returning to the field. According to the method, by directly sowing rice without reserving the rice field, the loss caused when crops cannot be planted on the reserved field can be reduced; meanwhile, the,transplanting, root breaking and reviving processes are not involved, early growth and quick tillering are facilitated, and the growth and development period is shortened; the same variety is sowed at the same time, and the growth and development of the directly sowed rice can be about 10 days shorter than that of transplanted rice.

Description

technical field [0001] The invention relates to the field of rice planting. Background technique [0002] Rice is the food crop with the largest planting area and the highest yield per unit area and total output in my country. In the production of food crops, the labor intensity of rice cultivation is the highest (mainly transplanting and raising seedlings), and with the development of rural economy and the adjustment of industrial structure, a large amount of labor is transferred to the secondary and tertiary industries. Artificial planting has the disadvantages of wasting seedling fields, labor and time, long seedling slowing period, and delayed growth period. Therefore, light cultivation techniques that simplify rice cultivation and reduce labor intensity are receiving more and more attention. Contents of the invention [0003] The object of the present invention is to provide a rice cultivation method, which has the advantages of labor saving, labor saving and seedlin...
