Embodiment 1

[0025] A kind of economical and high-quality cultivation method of machine-harvested ratooned rice which avoids mechanical rolling comprises the following steps:

[0026] 1. Site selection: The test site is set at Jiupu Village, Chidong Town, Qichun County, Huanggang City, southeastern Hubei.

[0027] 2. Variety selection: choose Liangyou 6326, a two-line hybrid rice variety that is widely planted as ratooning rice in Hubei Province.

[0028] 3. Sowing: Sow on March 23, 2018, avoid rainy days, choose sunny weather to sow, and build a dove cover to keep the seedlings warm to prevent the seedlings from being damaged by low temperature and chilling. The seedling age is 35 days.

[0029] 4. Transplanting: Reserve machine harvesting aisles for planting. According to the characteristics of mechanical harvesting in the first season, a 60cm wide row is reserved as a mechanical walkway when transplanting, so that the crawler of the harvester can just walk on this walkway when harvesti...

[0035] A kind of economical and high-quality cultivation method of machine-harvested ratooned rice which avoids mechanical rolling comprises the following steps:

[0036] 1. Site selection: The test site is set at Jiupu Village, Chidong Town, Qichun County, Huanggang City, southeastern Hubei.

[0037] 2. Variety selection: choose Yongyou 4949, an indica-japonica hybrid rice variety grown in a large area in Hubei Province as ratooning rice.

[0038] 3. Sowing: Sow on March 23, 2018, avoid rainy days, choose sunny weather to sow, and build a dove cover to keep the seedlings warm to prevent the seedlings from being damaged by low temperature and chilling. The seedling age is 35 days.

[0039] 4. Transplanting: Reserve machine harvesting aisles for planting.

Abstract

The invention discloses a machine-harvested ratooning rice cost-saving high-quality cultivation method avoiding mechanical rolling. The machine-harvested ratooning rice cost-saving high-quality cultivation method avoiding mechanical rolling comprises the steps of variety selection; sowing: sowing around March 20 every year; transplanting: reserving a mechanical harvesting walkway for planting, reserving a row with the width of 60 cm as a mechanical walkway during transplanting according to the mechanical harvesting characteristics of first season rice, so that a crawler just walks on the walkway during harvesting of the first season rice by the harvester; fertilizer application; water management; mechanical harvesting: when the maturity of the first season rice reaches about 90%, harvesting by using a crawler-type grain combine harvester, and harvesting by using the same harvester after regeneration season rice is completely mature; and integrated pest control. The mechanical harvesting walkway planting is reserved, so that the rolling damage to rice stubs caused by mechanical harvesting of the first season rice is avoided, ventilation and light transmission conditions of groups are improved, marginal effects of the first season rice and the regeneration season rice are promoted to the greatest extent, the annual yield of the mechanically harvested regeneration rice is not reduced on the premise that the planting density is reduced by 33.3%, the seed consumption and labor input are greatly reduced, and the quality of the regeneration season rice is improved.

Description

technical field [0001] The invention belongs to the technical field of crops, and in particular relates to a cost-saving and high-quality cultivation method of machine-harvested regenerated rice that avoids mechanical rolling. Background technique [0002] Raisoning rice refers to the planting mode of using the dormant buds surviving on the rice stubble after the first harvest, adopting certain cultivation and management measures to make them germinate into regeneration tillers, leading to earing, flowering, and fruiting, and then harvesting a season of rice. Raising rice has the advantages of short growth period, high daily output, low production cost, and high economic benefits. It is the best choice for the southern rice areas in my country where there is a surplus of heat for one-crop rice and insufficient heat for double-crop rice, and for double-crop rice areas where only one-season rice is grown. It is one of the effective measures to increase the multiple cropping ind...
