Abstract
The invention provides a high-yield planting method of hybrid rice, which specifically comprises the following steps: selecting land, preparing land, soaking seeds, sowing, managing in the field and harvesting, after more than 95% of seeds at the lower part of the hybrid rice spike are hardened, harvesting in sunny days, threshing and drying in the sun, and properly keeping, compared with the original hybrid rice, the hybrid rice of the invention has less seed consumption and reduces the planting cost; the fertilizer consumption is small, the non-stage fertilization is reasonable, the fertilizer consumption is reduced, and the planting cost is reduced; the cost is low, mechanical sowing, mechanical seedling raising, mechanical seedling transplanting and mechanical field management are realized, and the labor cost is reduced; the yield is high, and the yield of the single-cropping rice planted by the method reaches 500-600 kg.
Description
Technical Field
The invention relates to a high-yield planting method for hybrid rice, belonging to the technical field of hybrid rice.
Background
The hybrid rice is the first generation hybrid rice with heterosis produced by hybridizing two rice varieties with certain genetic difference and excellent character complementation. Generally, hybrid rice refers to the first generation hybrid formed by the hybridization of two sterile lines and restorer lines with the same genetic background. The large-area spread hybrid rice mainly uses the male sterile line of rice as a genetic tool. China is the first country in the world to successfully develop and promote hybrid rice. The hybrid rice has high individual heterozygosity, and hybrid progeny has character separation, so the seed production is needed year by year. The hybrid rice corresponds to conventional rice. In 2019, 10 and 21 to 22 months, the third generation hybrid rice is subjected to the first public test in the Qing Zhucun in Hengyang city, Hengnan county, Hunan province, and the yield per mu is 1046.3 kg. The third generation of hybrid rice technology is a genetic tool using genetic engineering male sterile line, which can theoretically find the other half suitable for the rice and generate excellent progeny.
Along with the improvement of the living standard of people in recent years, the social demand for high-quality special hybrid rice is larger and larger, the planting area of the high-quality hybrid rice is rapidly increased, along with the upgrading of special powder products for processing enterprises and the continuous modernization of processing technology, the modern powder making industry puts forward higher and higher requirements on the quality and the stability of large-batch commercial hybrid rice, northern farmers excessively apply chemical fertilizers to produce the hybrid rice with high protein content, so that not only soil hardening is caused, but also the utilization rate of nitrogen is low, a large amount of nitrogen fertilizers are lost, the environmental pollution is serious, along with the improvement of production conditions in vast rural areas, the yield level of the hybrid rice is continuously improved, the increase of planting density and biomass inevitably causes the deterioration of the micro-ecological environment of a canopy, and is influenced by various factors such as climate warming in winter in recent years, so as to cause the continuous occurrence of main plant diseases and, the high yield and stable yield of the hybrid rice are seriously influenced, the processing and the nutritional quality of the hybrid rice are reduced, a series of problems of environmental degradation, polluted water supply, reduced plant diversity, resistance generation of insects and the like are caused by blindly using pesticides, meanwhile, the pesticide residue in grains is also directly seriously exceeded, the sanitary quality is greatly influenced, and the food safety problem is very good.

(6) Harvesting: after more than 95% of seeds at the lower part of the hybrid rice ear are hardened, the hybrid rice is harvested in sunny days, threshed and dried in the sun, and then is properly preserved.
The soil solvent is prepared from the following raw materials in parts by weight: 10 parts of medical stone powder, 2 parts of potassium chloride, 6 parts of kaolin, 3 parts of attapulgite, 2 parts of weathered coal, 4 parts of zinc sulfate, 1 part of manganese sulfate, 2 parts of magnesium sulfate, 1 part of sodium selenite, 0.1 part of nanocarbon, 4 parts of brown sugar, 3 parts of eucalyptus oil, 2 parts of boric acid, 3 parts of alum, 3 parts of silane coupling agent KH5501 and a proper amount of water, dissolving the brown sugar and the boric acid in a proper amount of water, adding the nanocarbon and the medical stone powder, and uniformly dispersing to obtain a mixed solution; mixing zinc sulfate, manganese sulfate, magnesium sulfate, sodium selenite, alum, eucalyptus oil and a silane coupling agent KH550, heating to 60 ℃, and uniformly stirring for 10 minutes to obtain a mixture; mixing the mixed solution, the mixture and the rest components, uniformly stirring, granulating and drying to obtain the fertilizer.
The yield per mu of the hybrid rice cultivated by the method reaches 680 kilograms. Compared with the traditional cultivation of the land with the same fertility, the yield is increased by more than 30 percent.
By adopting the method, 150 mu of land is exemplarily planted in Guizhou area, and the average yield is 677.5kg/666.7m2Meanwhile, the lodging does not occur, and the average yield of the similar rice planted by adopting the conventional direct seeding technology is 647.3kg/666.7m2And approximately 20% lodging occurs; meanwhile, because a water layer is not established in the earlier stage of the method, the method has the advantage that three times of water irrigation are reduced compared with the conventional planting method, so that the method is relatively more suitable for the local areaFor direct sowing on land, the water can be saved by 100m3The above. In addition, the frequent temperature abnormality in Guizhou region greatly causes the disadvantages of rice growth; the field investigation of direct-seeded rice irrigated on the same day shows that the rice planted by the method has stronger growth vigor in the seedling stage; specifically, the average seedling height of the rice seedlings planted by the method is 5.9cm, the root length is 5.56cm, and the number of the roots is 6, while the seedling height of the rice seedlings directly sowed by the conventional method is 2.5cm, the longest root is 1.1cm, and the average number of the roots is 2.8. The rice dry direct seeding cultivation method can effectively solve the problems of low seedling rate of seeds, poor early-stage root system development, easy lodging in the later stage and the like in the dry direct seeding cultivation of the rice, and the rice seeds are sown in a shallow soil layer of 0.5-2.0 cm without establishing a water layer in the field in the early stage, so that the rice seeds emerge in an aerobic environment, the development of the root systems of the rice seedlings is facilitated, and the lodging resistance of the direct seeding rice in the later stage is improved.
