Cultivation method of no-tillage sowing oat and perennial pasture intercropping

Abstract

The invention particularly relates to a no-till planting oat and perennial grass intercropping cultivation method. The no-till planting oat and perennial grass intercropping cultivation method is mainly characterized by comprising the following steps of step 1, performing grazing on the perennial grass before oat planting; step 2, performing stubble cutting, ditching, planting, earth covering and suppression mechanical operation on the soil on the perennial grass through a no-till planter during the oat planting time which is from September fifteenth to thirtieth, wherein the ditching depth is 1 to 2 centimeters, the oat planting quantity is 135 to 180 kilograms every square hectometer, and the planting space is 12 to 18 centimeters; step 3, performing overgrazing on the perennial grass after the oat planting; step 4, performing rest-grazing on the perennial grass after the overgrazing; step 5, harvesting oats through a machine during the oat harvesting time which is from April tenth to fifteenth of the next year, wherein the oat stubble height is 10 to 15 cm; step 6, performing normal grazing management on the perennial grass after the oat harvesting. According to the no-till planting oat and perennial grass intercropping cultivation method, the flexibility of the agriculture and animal husbandry production is improved, the risk of the agriculture and animal husbandry production management is reduced, the diversified cultivation of grass, grain and livestock is performed, and the soil nutrient element, animal and microorganism quantity is improved.

Description

technical field [0001] The invention relates to a cultivation technique, in particular to a cultivation method for no-tillage sowing oats intercropped with perennial herbage. Background technique [0002] Grass field intercropping technology is called regenerative agriculture. The one-year crops are sown in the middle of perennial pastures with low-tillage or no-tillage seeders. During the growth of crops, perennial pastures remain dormant or crops are shaded to inhibit the growth of pastures. When crops dry or After harvest, perennial pastures resume growth (Millar G D and Badgery W B. Pasture cropping: a new approach to integrate crop and livestock farming systems. (Special Issue: Grain&Graze: an innovative triple bottom line approach to collaborative and multidisciplinary mixed-farming systems research, development and extension.)[J].Animal Production Science,2009,49,777-787.). In grass field intercropping technology, perennial grass and annual crops are grown without ga...
