黑龙江省牧草种子产业现状

牧草种子是改良退化草地、建植栽培草地，提高草地畜牧业生产力的物质基础。黑龙江省牧草种子本土化生产水平低，是长期制约当地草地畜牧业发展的关键因素之一。通过调研和查阅资料，目前全省已收集牧草种质资源2 000余份，育成国审牧草饲料品种19个，制定牧草种子生产相关地方标准9项。重点研究了苜蓿(Medicago sativa)良种繁育技术，并进行了推广应用，使苜蓿种子产量由原来的150 kg/hm2提高到225 kg/hm2。年生产各类牧草种子700 t，但现有的牧草种子生产远远满足不了发展需求，牧草种子产业仍存在法律、法规不健全、优良品种缺乏、机械化程度低等问题。

Current situation and development measures of herbage seed industry in Heilongjiang Province

Forage seed source is one of the most important factors on improving degenerated rangeland,establishing artificial grassland and raising pastural animal production.The local pasture and stock breeding development was inhibited in Heilongjiang for long time due to the low level of forage seed production.According to investigation and consulting on relevant data in Heilongjiang,there are that more than 2 000 forage germplasm resources have been collected;19 varieties have been officially recognized;9 local standards of forage seed productions have been established in Heilongjiang Province so far.In addition,the seed-breeding development of alfalfa(Medicago sativa) was especially studied;and the seed yield has been improved from 150 to 225 kg/ha.Although the annual seed yield in Heilongjiang is around 700 t,the existing forage seed production can hardly satisfy the requirement of pastural development.There are still many problems of forage seed production,i.e.imperfect laws and regulation,lack of good varieties,and low degree of mechanization,etc.
