一、试验目的近年,临夏川塬灌区复种饲草面积逐渐增大。主要复种作物是燕麦和箭舌碗豆。燕麦产草量较高,一般亩产鲜草3500—4500斤,缺点是耗地厉害,营养价值偏低,不够理想;箭舌豌豆营养丰富,也能养地,产草量却一般,大多亩产鲜草3000—3500斤,且易倒伏霉烂,仍不十分理想。本试验目的是寻求产草量高、养地作用强、营养丰富、不倒伏霉烂的复种饲草作物。二、试验方法和经过据青海省牧研所介绍,蚕豆种的变种饲用蚕豆(Vicia faba Var minor),又名“小粒蚕豆”,既能春播收籽,又可以头茬收草二茬收籽或头茬收籽二茬收草,还适宜复种。据
First, the purpose of the test In recent years, Linxia Chuan plateau irrigation area of multi-species forage grass gradually increased. The main crop is oatmeal and bowel beans. Oats higher yield, the general yield of 3500-4500 kg of fresh grass, the disadvantage is that consumption of powerful, low nutritional value, not ideal; tongue tongue pea nutritious, but also to raise grass, grass production is generally large Production of fresh 3000-3500 pounds, and easy loses mildew, still not very good. The purpose of this experiment is to find a multiple cropping forage crop that is high in grass yield, strong in raising land, rich in nutrients and not lumpy. Second, the test methods and after According to the introduction of pastoral research institute in Qinghai Province, broad bean varieties Vicia faba Var minor, also known as “small grain broad beans”, both spring seeding seed, but also the first crop stubble second harvest Seeds or the first crop stubble seeds received the second crop, but also suitable for multiple cropping. according to
