Problems solved by technology

[0003] The existing direct-directed rice cultivation method only adopts the method of soaking the seeds and then accelerating the germination during seed treatment, which is not conducive to the improvement of the germination rate of the seeds and the ability to resist diseases and insect pests, and thus is not conducive to the improvement of the yield.

Embodiment 1

[0023] A high-yield cultivation method for direct direct seeding of double-cropping rice, the steps are as follows:

[0024] 1) Variety selection: select early-maturing or mid-maturing varieties that have good cold resistance at seedling stage, early growth and rapid emergence, moderate tillering ability, strong disease resistance, short plants, and strong lodging resistance;

[0025] 2) Fine soil preparation: one month before sowing, irrigate and plow and bury the weeds, sprinkle lime and special farmyard manure, harrow the land 4 days before sowing until there is no water and weeds in the field, and then make a furrow, the height of the furrow is low The difference should not exceed 1 inch, and a furrow should be opened every 3 meters;

[0026] 3) Seed treatment and germination: The seeds are water-selected with salt water with a specific gravity of 1.3, and the wet seeds after water selection are tiled for electron beam radiation treatment. The electron beam radiation dose ...

Embodiment 2

[0037] 1) Variety selection: select early-maturing or mid-maturing varieties that have good cold resistance at seedling stage, early growth and rapid emergence, moderate tillering ability, strong disease resistance, short plants, and strong lodging resistance;

[0038] 2) Fine soil preparation: One month before sowing, irrigate and plow and bury the weeds, sprinkle lime and special farmyard manure, and harrow the field 5 days before sowing until there is no water and weeds in the field, and then make a furrow. The difference should not exceed 1 inch, and a furrow should be opened every 3.5 meters;

[0039] 3) Seed treatment and germination: The seeds are water-selected with salt water with a specific gravity of 1.4, and the wet seeds after water selection are tiled for electron beam radiation treatment. The electron beam radiation dose is controlled to 1.5kGy, and the radiation time is 8s. Then the seeds are spread in the sun for 1.5 days. The spread has the functions of promo...

Embodiment 3

[0050] A high-yield cultivation method for direct direct seeding of double-cropping rice, the steps are as follows:

[0051] 1) Variety selection: select early-maturing or mid-maturing varieties that have good cold resistance at seedling stage, early growth and rapid emergence, moderate tillering ability, strong disease resistance, short plants, and strong lodging resistance;

[0052] 2) Fine soil preparation: one month before sowing, irrigate and plow and bury weeds, sprinkle lime and special farmyard manure, and harrow the land 6 days before sowing until there is no water and weeds in the field, and then make a furrow. The difference should not exceed 1 inch, and a furrow should be opened every 4 meters;

[0053] 3) Seed treatment and germination: Use salt water with a specific gravity of 1.1.5 to water-select the seeds, spread the wet seeds after water-selection for electron beam radiation treatment, control the electron beam radiation dose to 2kGy, and the radiation time i...

Abstract

The invention discloses a direct-seeding high-yield cultivation method for double cropping rice. The method comprises the following steps: 1) variety selection; 2) fine soil preparation; 3) seed treatment and germination acceleration; 4) seeding; and 5) field management. Water selection is carried out on the seeds, the wet seeds after water selection are spread for electron beam radiation treatment, and then the seeds are tedded, tedding has the effects of promoting seed after-ripening and enzyme activity, reducing the content of germination inhibiting substances in the seeds, improving the germination rate, sterilizing and the like, the electron beam radiation treatment can induce the seeds and improve the seed activity to promote seed germination, then the seeds are placed in an oscillating electric field and oscillating alternating magnetic field environment, the permeability of the surfaces of the seeds is enhanced, the activity of various enzymes in the germinated seeds is further activated, the germination potential and germination rate of the seeds are increased, and the nutrient absorption capacity and stress resistance such as drought resistance, cold resistance and disease resistance of crops are improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a high-yield cultivation method for direct direct seeding of double-cropping rice. Background technique [0002] Direct seeding of rice is a cultivation method that directly sows seeds in the field without raising seedlings and transplanting. Large-scale direct seeding of rice can save a lot of labor and alleviate the contradiction of labor seasonal tension. It is of great significance to realize light, professional and large-scale rice production, and has broad prospects for promotion. However, compared with transplanted rice, direct-seeding rice has three major problems: difficulty in growing seedlings, heavy weed damage, and easy lodging. [0003] The existing direct-directed rice cultivation method only adopts the method of soaking the seeds and then accelerating germination during seed treatment, which is not conducive to the improvement of seed germination rate and r...
