吉林省多年生栽培草种区划研究报告

A REPORT OF STUDY ON THE DIVISION OF PERENNIAL CULTIVATED HERBAGE SPECIES INTO DISTRICTS IN JILIN PROVINCE

摘要:

本课题是农牧渔业部畜牧局1984年下达的科研项目。先后搜集整理了1923年以来我省多年生牧草的文献资料90多篇;考察了省内6个地区的牧草生产现状;设置了6处小区辅助试验点进行对比观察。根据上述资料的综合分析,确定了吉林省多年生栽培草种,区划为三个区,即西部平原羊草,苜蓿区;中部平原苜蓿、无芒雀麦区和东部山区、半山区胡枝子、苜蓿、无芒雀麦区。沙打旺和野大麦为本省辅助当家草种。

Abstract:

This research programme was assigned by the Animal Husbandry Bureau, Ministry of Agriculture, Animal Husbandry and Fisheries in 1984. 90 references related to perennial herbages of Jilin province since 1923 were collected, For ther more, present herbage production situation in 6 districts of the province were investigated and 6 supplementary plot experimental sites in different places were established and engaged in vation and comparison. On the basis of synthetically analysing aforementioned materials, we have identifyed the perennial cultivated herbage species of the province and divided the whole province into three herbage cultivated areas as follows:Chinese wildrye (Aneurolepidium chinese)——Alfalfa (Medicago stiva) area in western plain Alfalfa——Smooth brome grass (Bromus inermis) area in central plain and Shrub lispedeza (Lespedeza bicolor)——Alfalfa——Smooth bromegrass area in eastern moutain & semi-mountain area. All the species mentioned above are' head herbage species' of Jilin province. Astragalus adsurgens Pall. and Hordeum brevisubulatum (Trin) Link. are supplementary'head herbage species'
