Abstract

The technological scheme of cultivating re-planted rice includes transplanting rice seedling of premature rice variety in field; growing seedling of premature re-planted rice; harvesting mature premature rice and transplanting seedling of premature re-planted rice and harvesting the premature re-planted rice after 128 days. The present invention makes it possible to cultivate two crops of rice in northern area and three crops of rice in southern area in one year. The re-planted rice is cultivated without any fertilizer, herbicide and pesticide and thus is green rice.

Description

The cultural method of proliferation paddy rice

Technical field: the present invention relates to a kind of cultural method of paddy rice, especially the cultural method of proliferation paddy rice.

Prior art: at present, be a season vegetative period of paddy rice in the north now, in south was two seasons, since the transformation of the Nature weather now behind paddy rice harvesting apart from also having the regular hour frost season, wherein early stage paddy rice starch the back surely and be particularly suitable for growth and the maturation of proliferation paddy rice to stage of maturation, reach the generation of another paddy rice in season; Also do not have the application of cultural method in agricultural about the proliferation paddy rice now aspect the agricultural rice breed, therefore, the farmland does not also have to produce bigger economic worth in process of production.

Summary of the invention: the purpose of the cultural method of proliferation paddy rice of the present invention is: according to south and northern different weathers and temperature, utilize the characteristics of precocious paddy rice to realize the cultural method of above-mentioned proliferation paddy rice, can reach in the north reached in two seasons in south three season paddy rice production; The spike of rice of proliferation paddy rice can be ripe, makes the farmland produce bigger economic benefit in process of production, increases peasant's income; To achieve these goals, the technical scheme of the cultural method of proliferation paddy rice of the present invention is: cultivate rice shoot cold-resistant, precocious rice varieties earlier, rice shoot is inserted into the paddy field; The precocious paddy rice seedling of proliferation, the paddy rice of rice transplanting in early stage through tillering, educate fringe, earing, flowering, grouting, after productive phase, reaching maturation can gather in, about 2 centimetres in water is stayed in harvested paddy field; Guarantee after more than 40 days at the seeding stage of proliferation paddy rice, the rice shoot of proliferation paddy rice is inserted in harvested field; Also the rice shoot of proliferation paddy rice can be inserted in growing with the regeneration paddy rice of harvesting front and back rice root on every side or on the paddy rice pin, the rice root of death helps the nutrition supply of proliferation paddy rice and the effect of temperature protection after the harvesting in early stage; Proliferation paddy rice seedling is tillered after adapting to the field environmental temperature, later the water level in field is controlled at tillering stage to enter paddy rice about 8 centimetres and educate the fringe phase; The proliferation paddy rice begins grouting after educating fringe, earing, flowering, this moment, the field water level was controlled at about 2 centimetres, can enter productive phase in frost-free season behind the rice milking stage, paddy rice maturation after active accumulated temperature reaches 2450 ℃ in the vegetative period of whole paddy rice is carried out the harvesting of proliferation paddy rice; Even active accumulated temperature does not reach 2450 ℃ after proliferation rice milking stage 70%, also can gather in immature paddy rice fringe, be used for brewing spirit or process other feeds.

Embodiment: following cultural method to the proliferation paddy rice is described further: in the north be example was cultivated precocious rice varieties earlier on March 20 at the solar calendar in every year paddy rice seedling with the Liaoning Area, the length of time rice seedlings grow guarantees before May 3 rice shoot to be inserted into the land for growing field crops more than 40 days; The precocious paddy rice seedling of proliferation on May 20, after the paddy rice of rice transplanting in early stage was starched surely through productive phase, reaching maturation can gather in, and about 2 centimetres in water is stayed in harvested paddy field; Guarantee after more than 40 days at the seeding stage of proliferation paddy rice, the rice shoot of proliferation paddy rice is inserted in harvested field; Also the rice shoot of proliferation paddy rice can be inserted in growing with the regeneration paddy rice of harvesting front and back rice root on every side or on the paddy rice pin, the rice root of death helps the nutrition supply of proliferation paddy rice and the effect of temperature protection after the harvesting in early stage; Proliferation paddy rice seedling is tillered after adapting to the field environmental temperature, later the water level in field is controlled at tillering stage to enter paddy rice about 8 centimetres and educate the fringe phase; The proliferation paddy rice begins grouting after educating fringe, earing, flowering, this moment, the field water level was controlled at about 2 centimetres, can enter productive phase in frost-free season behind the rice milking stage, paddy rice maturation after active accumulated temperature reaches 2450 ℃ in the vegetative period of whole paddy rice is carried out the harvesting of proliferation paddy rice; Even active accumulated temperature does not reach 2450 ℃ after proliferation rice milking stage 70%, also can gather in immature paddy rice fringe, be used for brewing spirit or process other feeds; , can grow seedlings according to this method, rice transplanting according to when the variation of ground temperature in south, carry out the enforcement of third quarter paddy rice.

Claims

1, the cultural method of a kind of proliferation paddy rice is: cultivate rice shoot cold-resistant, precocious rice varieties earlier, rice shoot is inserted into the paddy field; The precocious paddy rice seedling of proliferation, the paddy rice of rice transplanting in early stage through tillering, educate fringe, earing, flowering, grouting, after productive phase, reaching maturation can gather in, about 2 centimetres in water is stayed in harvested paddy field; Guarantee after more than 40 days at the seeding stage of proliferation paddy rice, the rice shoot of proliferation paddy rice is inserted in harvested field; Also the rice shoot of proliferation paddy rice can be inserted in growing with the regeneration paddy rice of harvesting front and back rice root on every side or on the paddy rice pin, the rice root of death helps the nutrition supply of proliferation paddy rice and the effect of temperature protection after the harvesting in early stage; Proliferation paddy rice seedling is tillered after adapting to the field environmental temperature, later the water level in field is controlled at tillering stage to enter paddy rice about 8 centimetres and educate the fringe phase; The proliferation paddy rice begins grouting after educating fringe, earing, flowering, this moment, the field water level was controlled at about 2 centimetres, can enter productive phase in frost-free season behind the rice milking stage, paddy rice maturation after active accumulated temperature reaches 2450 ℃ in the vegetative period of whole paddy rice.
