Cultivation method based on rice and vegetable rotation

Abstract

The invention provides a cultivation method based on rice and vegetable rotation. A first crop is rice, a second crop is early-maturing cauliflowers and a third crop is celeries, and one rice and vegetable rotation production cycle is completed through sequential planting of the rice, the early-maturing cauliflowers and the celeries. Specifically speaking, rice seedlings are raised in the midmonth of March, rice fields are turned over and then the rice seedlings are transplanted in the midmonth of April, and the rice is harvested from last ten-day of July to first ten-day of August; the rice fields are turned over, flattened and made into ridges in first ten-day and midmonth of August and then the cauliflowers are planted, and the cauliflowers are harvested from last ten-day of November to first ten-day of December; the celeries are planted from last ten-day of November to first ten-day of December, and after the celeries are harvested in first ten-day to midmonth of April, one rice and vegetable rotation production cycle is completed. According to the cultivation method based on rice and vegetable rotation, transitions of rice and vegetable rotation are combined closely, and the land utilization rate and the multiple crop index are improved; meanwhile, diseases and insect pests of the rice and the celeries are reduced; in addition, through the rice and vegetable rotation, especially through the manner that the celeries are directly planted after the early-maturing cauliflowers are harvested, frequencies of farmland ploughing and water and soil loss are reduced, labor intensity is reduced, and the purposes of increasing incomes, reducing expenses and promoting sustainable development are achieved.

Description

【Technical Field】 [0001] The invention relates to a high-efficiency, labor-saving cultivation method based on rice-vegetable rotation, and belongs to the technical field of agriculture. 【Background technique】 [0002] In order to increase the multiple crop index of the field and reduce the production cost, the southern vegetable field generally adopts double cropping or even multiple cropping in a year, which leads to the increase of the number of pathogenic bacteria in the field and the toxic substances secreted by crop roots, the imbalance of soil nutrition, the deterioration of physical and chemical properties, and it is beneficial. Microorganisms and numbers are reduced, fertility is reduced, diseases and insect pests are serious, and planting benefits are reduced. [0003] In view of this, the inventor of the present invention conducted in-depth research on the shortcomings of the prior art, which led to this case. [Content of the invention] [0004] The technical problem to b...
