Taicang white garlic-rice double-cropping-system paddy-upland rotation high-yield and efficient planting technology

Abstract

The invention discloses a Taicang white garlic-rice double-cropping-system paddy-upland rotation high-yield and efficient planting technology which is characterized by comprising the following implementation steps that straw coverage no-tillage cultivation is adopted after rice is harvested for 5-10d; all rice straws are returned to a field; a base fertilizer is applied sufficiently; Taicang white garlic is sown with the density of 300000-375000 plants / hectare; a seedling fertilizer, a winter fertilizer and a bolting fertilizer are applied additionally after the garlic is sown; garlic sprouts are started to be harvested in early May; garlic heads are harvested at the end of May; the field is ploughed and upturned soil is sunned at the beginning of June; the rice is sown directly with the sowing amount of 750000kg / hectare; water-saving shallow-wet irrigation water management is conducted on the rice field; a nitrogen-saving, phosphorus-increasing and potassium-supplementing balance formula fertilizer applying technology is implemented; and the rice is harvested in a yellow ripening stage after dew is dried. The technology can reduce multiple soil-borne diseases due to continuous cropping, improves a soil structure, increases a fertilizer utilization rate, reduces field pollution, improves the overall grain production capability stably and facilitates efficiency enhancement of agriculture and income growth of farmers.

Description

Technical field: [0001] The invention relates to the planting technology of Taicang white garlic and rice, in particular to the high-yield and high-efficiency planting technology of "Taicang white garlic-rice" two-ripening paddy and dry rotation. Background technique: [0002] In recent years, due to the rapid economic and social development of land demand, the area of ​​agricultural land has become less and less. In order to improve the efficiency of grain planting per unit area, a large amount of chemical fertilizers and pesticides have been invested all the year round, resulting in the decline of soil fertility and serious agricultural pollution. This traditional Traditional agricultural production methods are not conducive to the organic combination of resource conservation, agricultural efficiency, and environmental friendliness. For this reason, many places, especially the main grain-producing areas, blindly shrink grain and expand the economy to increase the added val...

Problems solved by technology

However, this practice of abandoning food production and blindly pursuing economic value is very likely to pose a serious threat to national food security

The use of rice and economic crop rotation is a practical and effective way to solve the above contradictions, but there are many difficulties due to a series of problems such as crop growing season contradictions, stubble connection, field requirements and farmland infrastructure.
