Embodiment 1

[0031] S1. Select ultra-high-yielding varieties with strong regeneration ability, good stress resistance, high-quality edible rice, and a full growth period of 140-160 days as mid-season rice and ratooning rice varieties; the rice varieties are Zhunliangyou 608 and Shenliangyou 5814.

[0032] Use 25% prochloraz EC 1000 times solution + 5% diconazole 500 times solution to disinfect and soak the seeds intermittently to promote strong buds, choose a rice field with fertile soil, high terrain, leeward and sunny and easy to manage as the seedling bed, 4 Seedlings are planted in the middle and late months of the month; the seedlings are dry seedlings, and the seedlings are 20 days old and the leaf age is 3.5 leaves.

[0033] S2. In early May, plant mid-season rice in red soil areas by transplanting or throwing seedlings, and harvest mid-season rice in late August; the remaining stubble will be regenerated into ratooning rice, and field management will be strengthened, and rattan rice...

Abstract

The invention discloses a grain-rapeseed double-harvesting planting method for a red-soil rice field. The method comprises the steps: (1) selecting a middle-season rice and ratoon rice variety, planting middle-season rice in a red-soil region in a rice seedling transplanting or throwing manner at the first ten days of May, and reaping the middle-season rice at the last ten days of August; and carrying out stubble-remaining regrowing so as to obtain ratoon rice, strengthening field management, and reaping the ratoon rice at the last ten days of October; and (2) selecting a hybridized double-low rape variety, and carrying out interplanting 5 to 7 days before reaping the ratoon rice at the last ten days of October; and carrying out mechanical harvesting and threshing when rape pods of an entire rape field are yellow and seed coats are black brown from the end of April to the beginning of May in an ensuing year. According to the method, on one hand, high and stable yielding of rice and rape can be simultaneously guaranteed from planting time; meanwhile, the middle-season rice is planted in advance by 20 to 30 days (the first or middle ten days of May) in this research, so that the condition that the ratoon rice is reaped at the end of October is ensured, thus, sufficient planting time for rape planting is set aside, and the planting of the middle-season rice is not affected after the rape is reaped; and bumper harvest in both grains and rapeseed is expected.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a method for double-harvest planting of rice and oil in red soil rice fields. Background technique [0002] According to rough statistics, there are nearly 0.13 to 20 million hm in southern my country 2 Idle fields in winter, including Hunan, Jiangxi, Guangdong and Guangxi 666.7×10 4 hm 2 Left and right, its light, temperature, water, and soil resources are not fully utilized. Rapeseed is the main oil-bearing crop in southern my country, and it is mainly rotated with rice, cotton and other crops for multiple cropping. At present, the main grain and oil planting mode in red soil areas is generally to plant rapeseed, soybeans, peanuts and other oil-bearing crops in dry land, while early and late rice, mid-season rice, etc. are mainly planted in paddy fields. For food crops, the mode of grain-oil rotation in paddy fields is mainly concentrated in the mode of middle...
