Embodiment 1

[0017] A kind of regeneration rice cultivation technique, comprises the steps:

[0018] S1. Plant the ratooning rice in an area with suitable temperature, light and water conditions, cut off the water and dry the field 7 days before the maturity of the first crop rice, cut off only the upper 2 / 3 of the rice plant, collect the rice ears, keep the axillary buds, and leave The lower 1 / 3 plants and roots;

[0019] S2. Remove the sick and rotten root system, leave a healthy root system, remove weeds in time, straighten the root system, and within 2 days of harvesting the first season rice, apply 5 kg / mu of urea, 8 kg / mu of potassium chloride and compound fertilizer per mu of paddy field 11kg / mu, irrigated, and then the axillary buds grow and develop to form second crop rice;

[0020] S3. Spray 902 gibberellin 3g / acre once about 1 week after the growth of the second-season rice to stimulate the growth of leaves and buds. During the growth of the second-season rice, spray imidaclopr...

Abstract

The invention discloses a cultivation process of ratooning rice. The cultivation process of ratooning rice comprises the following steps of Step 1, cutting off water supply to dry the land at 7 days before first-crop rice is mature, only cutting the upper 2/3 parts of rice plants, collecting rice ears, remaining axillary buds, and leaving the lower 1/3 parts of plants and root systems; Step 2, with two days of first-crop rice harvesting, applying 5 to 15 kg of urea, 5 to 10 kg of potassium chloride and 11 to 15 kg of compound fertilizers into per mu of rice field, performing irrigation, and then growing the axillary buds to form second-crop rice; and Step 3, spraying 902 gibberellins once about 1 week growth of the two-season rice at a concentration of 3 to 5g/mu so as to stimulate the growth of leaves and buds, spraying imidacloprid, buprofezin and 920 growth regulators during the growth period of the second-crop rice, and performing harvesting when the yellowing rate of grains of thesecond-crop rice reaches 95 percent or higher. The cultivation process of ratooning rice has the advantages that the process is simple; a proper number of special fertilizers are applied before the first-crop rice is mature; the survival and the germination of the axillary buds are also facilitated; the 902 gibberellins are sprayed once about 1 week of growth of the second-crop rice so as to stimulate the growth of the leaves and the buds; and the 920 growth regulators are favorable for rapid and healthy growth of the second-crop rice.

Description

technical field [0001] The invention belongs to the technical field of ratooning rice cultivation, and more specifically relates to a ratooning rice cultivation technique. Background technique [0002] Raisoning rice refers to middle-season rice plus storage ratooning rice, which is a kind of rice that uses the regeneration characteristics of rice and adopts certain cultivation and management measures to make the dormant buds on the rice piles after the harvest of the first season rice germinate and grow, and then obtain the ear of the regeneration season rice. type. The existing cultivation method of ratooning rice is relatively complicated, and it is not conducive to the secondary development of ratooning rice after harvesting. Therefore, we propose a cultivation process of ratooning rice. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a regeneration rice cultivation technique. [0004]...
