[0022]Example 1

[0023]A high-yield cultivation method of double-season rice broadcast, steps are as follows:

[0024]1) Variety selection: Choosing the seedling stage is good, early early birth, moderate tillering strength, strong disease resistance, relatively short, anti-crowd;

[0025]2) Finely and finish: Irrigation plowed for a month before sowing, turbur, throwing the lime and special farmyard fertilizer, 4 days before sowing to the field without strengthening water and weeds, then make a high and low Do not exceed 1 inches every 3 meters;

[0026]3) Seed treatment and germination: The seeds are sealed with a salt of 1.3, and the wet seed after the water is selected, and the electron beam radiation is controlled. The electron beam radiation dose is controlled to 1 kGy, and the radiation time is 6s, then 1 day of seed boat, the boiling has the activity of the seeds and enzymes to promote seeds, reducing the seed inhibition of germination substances, improving germination rate and sterili...

[0037]1) Variety selection: Choosing the seedling stage is good, early early birth, moderate tillering strength, strong disease resistance, relatively short, anti-crowd;

[0038]2) Fine place: Irrigation plowed a month before sowing, turbur, throw the weeds, throw the lime and special farm childhood fertilizer, 5 days before sowing to the field without strengthening water and weeds, then do the high and low Do not exceed 1 inches of differentiation, open a trench every 3.5 meters;

[0039]3) Seed processing and genset: The seeds are selected from the salt water of 1.4, and the wet seed after the water is selected to carry out the electron beam radiation treatment, and the electron beam radiation dose is controlled to 1.5 kGy, and the radiation time is 8 s. Then, the seed boat is 1.5 days, and the boiling has the activity of the seeds and enzymes, and the seed inhibits the content of the germination, improves germination rate and sterilization, etc., electron beam radiation ...

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...
