Embodiment 1

[0024] (1) Soil preparation and fertilization: Arrow tongue pea has small seeds, slender seedlings, and weak top soil strength. Arrow tongue pea planting ground should be deeply plowed and raked, crushed soil clods, leveled ground, water storage and moisture conservation, so that the soil is empty at the top and firm at the bottom , to create good soil conditions for the emergence of arrow tongue pea seeds. Combined with plowing, depending on the soil fertility, apply enough base fertilizer. Generally, 1200-1400kg of organic fertilizer or 60-75kg of compound fertilizer is applied per mu;

[0025] (2) Sowing period: Arrow tongue pea likes a warm and humid climate. The optimum temperature for germination of arrow tongue pea seeds is above 13°C, and seedlings can grow well above 10°C. Therefore, the sowing period of arrow tongue pea is longer, and it can be sown in both autumn and spring. Autumn sowing of arrow tongue peas is generally available from mid-to-late July to early A...

Abstract

The invention discloses a planting method of winter highland barley multiple cropping Vicia sativa. The method comprises the following steps: leveling a land parcel after winter highland barley is harvested, storing water and preserving moisture, and applying base fertilizer; sowing the Vicia sativa from mid-to-late July to early August, wherein the Vicia sativa can be single sowed or mixed sown;when the seeds are harvested, the seeding rate per mu is 12.0-14.0 kg; immediately irrigating after the winter highland barley is harvested, and thoroughly irrigating once every 15 days: timely dressing 5-10kg of nitrogen fertilizer per mu after the seedlings emerge from the Vicia sativa; spraying pesticide before sowing and after seedling emergence of the Vicia sativa. The method makes full use of free land parcels after winter highland barley harvest, promotes farmland material circulation and improves forage grass yield and land utilization rate through multiple cropping of Vicia sativa, and has very important significance for increasing income of local farmers and herdsmen and improving ecological environment.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a planting method for double-planting arrow tongue pea with winter green barley. Background technique [0002] Highland barley is the main food crop in Tibet and an important basis for ensuring food security. According to the sowing season, it can be divided into spring highland barley and winter highland barley. Spring highland barley is mainly distributed in valley farming areas above 4,500 meters above sea level, sown in April and harvested in September; winter highland barley is distributed in mountainous areas, mid-mountain areas and river valleys below 4,500 meters above sea level. District, sowed in October, harvested at the end of July and early August of the following year. The winter barley planting area in Tibet has the natural conditions of high temperature, good water and heat resources, and a long frost-free period. However, in terms of heat condition...
