1 前言近几年来,我省紫花苜蓿的种植面积不断增大,但种子短缺是影响当前苜蓿生产的重要因素。如何提高单位面积产种量是目前急待解决的问题。根据紫花苜蓿的生物学特性,我们在紫花苜蓿采种田上进行了不同播种量的小区试验。旨在提高种子单产,为大面积生产紫花苜蓿种子提供依据。
1 Introduction In recent years, alfalfa planting area in our province continues to increase, but the shortage of seeds is an important factor affecting the current alfalfa production. How to improve the yield per unit area is an urgent issue to be solved. According to the biological characteristics of alfalfa, we conducted plot tests of different sowing rates on the field of alfalfa harvesting. Aims to improve seed yield, provide the basis for large-scale production of alfalfa seeds.
