Crop rotation planting method for forage crops and grain crops

Abstract

The invention provides a crop rotation planting method for forage crops and grain crops. The crop rotation planting method includes the steps of field arrangement, wherein planting belts are established in a field as required, different crops are planted on the adjacent planting belts, ryegrass or maize is alternately planted on the planting belts A according to the season, endives are planted on the planting belts B, and the planting belts A and the planting belts B are subjected to cross planting at intervals; planting time arrangement; field management. According to the crop rotation planting method, forage grass production serves as main aim, grain production serves as the auxiliary aim, forage (the ryegrass, the endives and the maize) serve as main output products, and in winter and autumn, the ryegrass and the endives can supply a large amount of forage to meet the requirements of animal production; in summer, the endives are interplanted between maize rows, field ventilation can be added, ventilation of a maize field is good, and the per unit area yield is high. By means of the crop rotation planting method, the labor requirement degree of agricultural production is reduced, the forage supplying amount is increased, and local animal husbandry development can be achieved.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a method for planting crops in rotation with forage crops and food crops. Background technique [0002] The hilly area of ​​the Sichuan Basin is warm and humid throughout the year, with an average annual temperature of 16-18°C, a duration of 240-280 days for a daily average temperature ≥ 10°C, and an accumulated temperature of 4000-6000°C. The daily temperature range is small, but the annual temperature range is large. Hot, frost-free period 230-340d. The traditional planting patterns in this area are mainly wheat-jade / sweet (winter wheat and corn are interplanted with sweet potatoes) and wheat-jade / bean (winter wheat and corn are interplanted with soybeans). These two traditional planting modes are mainly for harvesting grains, which are slightly contradictory to the meteorological conditions in the Sichuan Basin, where there are many clouds, few sunny days and short sunshine ...

AI Technical Summary

Problems solved by technology

In addition, the traditional wheat-jade / sweet and wheat-jade / bean rotation patterns have a large demand for labor force, which is in contradiction with the reality that the rural working population has declined sharply at this stage and the labor force is seriously insufficient

Moreover, the forage production capacity of the traditional planting mode wheat-jade / sweet and wheat-jade / bean rotation mode is low, which is not suitable for the rapid development of local animal husbandry.

In recent years, the sown area of ​​wheat in hilly areas has declined severely, and the proportion of interplanted sweet potatoes and soybeans in corn fields is also decreasing. Not planting crops in winter is a great waste of light and heat resources in hilly areas, and it also leads to increased soil erosion in slope farmland.

In addition, in summer, the field of purely planted corn has poor ventilation, and the yield per unit area of ​​corn is low.
