Rice field-upland field rotation planting method for broad beans, potatoes and rice

Abstract

The invention discloses a rice field-upland field rotation planting method for broad beans, potatoes and rice. The method comprises the following steps: (1) midseason rice production: planting midseason rice in well ploughed rice fields; (2) ratoon rice production: instantly irrigating the fields and seeding after midseason rice harvest, draining water in the rice fields after ratoon rice harvest; (3) broad bean sowing: seeding in the drained rice fields in a mode of seeding two lines while skipping two lines; (4) potato sowing: seeding in the idle lines after broad bean sowing, and enabling straw to be covered on the fields after seeding; and (5) harvest: harvesting fresh broad bean pods and the potatoes on April 27th to May 3rd next year. According to the rice field-upland field rotation planting method, crop economy benefits of limited land resources and temperature and light utilization of crops are organically combined to the largest extent according to eco-climate conditions of Chongqing Municipality, the complementary advantages of growth periods, growth vigor and water-fertilizer utilization and the like of the rice, the broad beans and the potatoes are ingeniously utilized, crop rotation and relay intercropping are arranged reasonably, light and temperature resources are fully effectively utilized, the complementary advantages among the crops are utilized, agricultural planting benefits are maximized, and the method is easily understood and saves labor.

Description

technical field [0001] The invention relates to a method for planting crops, in particular to a method for planting broad beans, potatoes and rice in paddy and upland rotation. Background technique [0002] Crop rotation is a planting method in which different crops or multiple crop combinations are planted sequentially between seasons or years on the same field. Reasonable crop rotation can improve soil, improve soil fertility, reduce the damage of diseases, insect pests and weeds, and ensure crops output and improve economic efficiency. As the main food crop of human beings, rice can be divided into early rice, middle rice and late rice according to their different responses to light. Middle rice is between early rice and late rice. It generally matures in early autumn and is more commonly planted in the middle and lower reaches of the Yangtze River. After the existing rice is ripe and harvested, the paddy field is generally idle, or the paddy field is plowed and then wh...

AI Technical Summary

Problems solved by technology

There are several disadvantages in rice-rape rotation, rice-wheat rotation or rice-wheat rotation or rotation with other crops: 1. The stubble connection is not tight, and the light and temperature resources cannot be used to the maximum; 2. The maximum economic benefits of the existing land resources cannot be fully utilized; 3. The complementary advantages of crop rotation or intercropping cannot be effectively exploited
