1.事先要了解草种性能 目前牧草种子很多,分别属于豆科、禾本科、蓼科、紫草科、菊科、苋科等不同种,同一种又有不同品种,不同品种的适应环境条件及利用方式也不同,一要从对环境条件的要求考虑,有的能适应当地环境条件,有的却不能。我们要切实根据当地水、热、光、土等具体情况来选择相应牧草,否则,会失败。如同样种豆科牧草,在豫南信阳地区种植白三叶好于紫花苜蓿,但在豫北太行山区种紫花苜蓿则好于白三叶,这是由于紫花苜蓿能适应豫北太行山区干燥、降水适中及土壤中性或中性偏碱条件,但不能适应豫南信阳地区高温高湿、降雨量偏大 1. In advance to understand the performance of grass grasses a lot of current forage, belonging to the legumes, grasses, Polygonaceae, Boraginaceae, Compositae, Amaranthus and other different species, the same species have different varieties of different adaptation to environmental conditions And the use of different ways, one from the environmental requirements of the consideration, and some can adapt to the local environmental conditions, while others can not. We must effectively according to the local water, heat, light, soil and other specific circumstances to choose the corresponding grass, otherwise, will fail. For example, leguminous forage was planted better in white clover than in alfalfa in Xinyang area in southern Henan, but alfalfa was better than white clover in the Taihang Mountains in the north of Henan Province. This is because alfalfa can adapt to the dry, Precipitation moderate and neutral or alkaline soil alkaline conditions, but can not adapt to Xinyang, southern Henan region, high temperature and humidity, rainfall is too large
