一、前言聚合草是一种产量高,营养好,深受贫下中农欢迎的多年生高产饲料作物。我省1977年试种成功,现已在全省推广,种植面积不断扩大。但是,就近几年的栽培情况看,还普遍存在着越冬的问题。聚合草在越冬中,常因遭受冻害而造成大部或全部死亡,从而降低了产量,影响了推广种植。我们遵照毛主席“一切实际工作者必须向下作调查”,“要坚持群众路线,遇事多和群众商量”的教导,于1976年的7—8月间到我省部分地区的八个单位,调查了聚合草越冬的问题。现将各地越冬情况,冻害原因及予防措施等有关问题报告于下,以供参考。在进行这项调查工作中,得到了省农牧局、绥化县畜牧科等单位的大力支持与协助,在此表示衷心感谢。
I. INTRODUCTION Aggregate grass is a perennial high-yield forage crop with high yield, good nutrition and deep poverty. Successfully cultivated in 1977 in our province has been promoted in the province, growing area planted. However, in the recent years of cultivation, there is also a general problem of overwintering. Poly grass in the winter, often because of frost damage caused most or all of the death, thereby reducing the yield, affecting the promotion of planting. In accordance with the teachings of Chairman Mao, “All actual workers must investigate downwards,” “We must persevere in the mass line and meet with the masses and discuss with the masses.” In July-August of 1976, we went to eight units in parts of our province , Investigated the problem of polymerization grass overwintering. Now overwintering around the situation, the causes of frost damage and preventive measures and other related issues reported below, for reference. In carrying out this investigation, we are greatly grateful for the strong support and assistance from the Provincial Bureau of Animal Husbandry and the Animal Husbandry Department of Suihua County.
