Problems solved by technology

However, the decomposing process of rice straw returning to the field is long, which has a certain impact on the planting and growth of the subsequent crop of wheat and rice, which in turn affects the yield and economic output, and greatly affects farmers' acceptance of and enthusiasm for implementing straw returning measures.

Embodiment 1

[0023] The rice-cauliflower (earthworm) model is implemented in Chongming Island. The average winter temperature of Chongming Island is 2.8°C, and the extreme minimum temperature on historical days is -10.5°C, which meets the conditions for open-air planting of cold-resistant vegetables. Specifically, start rice seedling cultivation in mid-to-late April, transplant rice seedlings by machine in mid-to-late October, and harvest rice when it is mature in mid-to-late October, and return the rice straw to the field in full by chopping (8-10cm) without straw transportation or burning. , and does not affect the planting and field management of the next crop of rice and vegetables; at the same time, cauliflower seedlings were raised in early October, and 800 kg of organic fertilizer was applied per mu of land in early November. Earthworm seedlings are 50 kg, and cauliflower is harvested from late April to early May of the following year, and earthworms are harvested in the field in ear...

Embodiment 2

[0027] The rice-potato (earthworm) model is implemented in Zhuanghang Town, Fengxian District. The average winter temperature in Fengxian District is 5.8°C, and the extreme minimum temperature is -7°C, which meets the conditions for outdoor planting of cold-resistant vegetables. Specifically, start rice seedling raising in late April, transplant rice seedlings by machine in late May, and harvest rice when it is mature in mid-to-late October, and return the rice straws to the field in full by chopping (8-10cm) without straw transportation or burning. And it will not affect the planting and field management of rice and vegetables for the next stubble; at the same time, put 50 kg of earthworm seedlings per mu of land, apply 800 kg of organic fertilizer per mu of land in late December, and start potato tuber seedlings in early January after plowing the whole border For planting, potatoes are harvested in early and mid-May of the following year, and earthworms are harvested in late ...

Embodiment 3

[0031] The rice-spinach (earthworm) model is implemented in Jiaxing, Zhejiang, where the average temperature in winter in Jiaxing is 5-12°C, which meets the conditions for open-air planting of cold-resistant vegetables. Specifically, start rice seedling cultivation in mid-to-late April, transplant rice seedlings by machine in mid-to-late October, and harvest rice when it is mature in mid-to-late October, and return the rice straw to the field in full by chopping (8-10cm) without straw transportation or burning. , and does not affect the planting and field management of the next crop of rice and vegetables; apply 1,000 kg of organic fertilizer per mu in late October, sow spinach in early November, and put 60 kg of earthworm seedlings in each mu of land, and harvest in late December spinach. Sow another batch of spinach in early March of the following year, harvest spinach in late April, and harvest earthworms in the field in early May.

Abstract

The invention belongs to the technical field of agriculture and particularly relates to a method for paddy-upland rotation rice and vegetable planting. The method comprises the steps of planting rice in a first cut, causing rice straw generated by rice harvesting to perform total crop return, planting cold-resistant vegetables in a second cut, and causing residual vegetables leaves to remain in the fields directly. The production cycle of paddy-upland rotation is finished through the rice and the cold-resistant vegetables, a certain amount of organic fertilizer is applied while straw returns to fields, and earthworms which are the most valuable soil animals in the earth are added. The rice-vegetable-earthworm harvesting is achieved, in-situ organism treatment of crop straw and residual leaves can be achieved, the fertilizer use amount can be reduced, the unit land output effect is improved, and the goals of income increase, expenditure reduction and green sustainable development are achieved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for planting rice and vegetables in paddy and dry rotation. Background technique [0002] The Yangtze River Delta region is my country's "land of fish and rice". The rice and wheat rotation is the main planting mode for food production. A large amount of straw is produced while the grain is high, which brings great pollution. In recent years, my country has tried to solve straw pollution. and comprehensive utilization, to achieve the goal of agricultural green production, a series of policies and measures have been formulated, and the research on comprehensive utilization of straw has become a hot spot. Among them, returning to the field is the most efficient, economical and effective. However, the decomposing process of rice straw returning to the field is long, which has a certain impact on the planting and growth of the subsequent wheat and rice, which ...
