Embodiment 1

[0034] Embodiment 1 and embodiment 2 all take traditional transplanting ratooned rice as contrast.

[0035] Example 1:

[0036] A high-yield cultivation method for live-directed regenerated rice, the steps of which are:

[0037] 1. Location selection:

[0038] The cultivation test site is scheduled to be located in Jiupu Village, Chidong Town, Qichun County, Huanggang City (30°14′N, 115°25′E). The area has good ecological conditions, flat terrain, good water conservancy facilities, and a good drainage and irrigation system. The main rice producing area in southeast Hubei.

[0039] 2. Variety selection:

[0040] The conventional rice variety Huanghuazhan was used.

[0041] 3. Fine land preparation:

[0042] Fifteen days before sowing, irrigate and plow and bury the weeds, and 3 days before sowing, rake the ground until there is no water and weeds in the field.

[0043] 4. Disinfection and germination:

[0044] First soak the seeds in the disinfectant solution of 500 time...

Embodiment 2

[0060] A high-yield cultivation method for live-directed regenerated rice, the steps of which are:

[0061] 1. Location selection:

[0062] The cultivation test site is scheduled to be located in Jiupu Village, Chidong Town, Qichun County, Huanggang City (30°14′N, 115°25′E). The area has good ecological conditions, flat terrain, good water conservancy facilities, and a good drainage and irrigation system. The main rice producing area in southeast Hubei.

[0063] 2. Variety selection:

[0064] The hybrid rice variety Tianyou Huazhan was selected.

[0065] 3. Fine land preparation:

[0066] Fifteen days before sowing, irrigate and plow and bury the weeds, and 3 days before sowing, rake the ground until there is no water and weeds in the field.

[0067] 4. Disinfection and germination:

[0068] Seeds are soaked in the disinfectant of 500 times of mass concentration prepared by 40% Dover WP or 50% Dover WP (200 grams of 40% Dover WP or 50% Dover WP mixed with water 100 Soak ...

Abstract

The invention discloses a high-yield cultivation method for direct seeding regeneration paddy rice. The method comprises steps: 1, selecting a variety; 2, performing intensive soil preparation; 3, disinfecting and accelerating germination; 4, sowing; 5, removing weeds; 6, performing fertilization management; 7, performing moisture management; 8, harvesting in a first season; 9, performing integrated pest control. On the premise of ensuring grain output, the method is easy to apply, simple to operate, and reduces labor input, improves planting efficiency, increases income of farmers, and opens up a new approach for development of regeneration paddy rice.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and more specifically relates to a high-yield cultivation method for live-directed regenerated rice. Background technique [0002] Rice regeneration refers to a season of rice harvested by adopting certain cultivation measures to make the dormant buds on the rice piles germinate and grow into spikes after the harvest of the first season of rice. Ragnarok rice has the advantages of short growth period, high daily output, provincial planting, labor saving, low production cost, and high economic benefit. It is an area and a double-cropping rice area in southern rice areas where there is excess heat for one-cropping rice and insufficient heat for double-cropping rice. It is one of the measures to increase the multiple cropping index in paddy fields that only plant one season of mid-season rice, and to increase the rice yield per unit area of ​​paddy fields and economic income. After the 198...
