为解决干旱影响小麦正常播种的问题,山东淄博市张店区沣水镇农技站于1989年秋种时将2BX-9A型谷物播种机改装成旱田小麦水播耧,当年推广应用了280多公顷。用旱田小麦水播耧播种的好处:首先是创造了良好的土壤墒情,确保了小麦一播全苗,充分利用了冬前降水、光照和温度资源培育了壮苗,植株发育好。第二,增产幅度大,效益显著。用改装的旱田小麦水播耧播种小麦,每公顷产量3000～3750千克,最高的达到4500千克,平均比同时干播增产81%,每公顷还节约麦种45～75千克,每公顷可增加纯收益579元,经济效益和社会效益显著。
In order to solve the problem of drought affecting the normal sowing of wheat, the 2BX-9A grain seeder was converted into wheat sowing water for dry land in the autumn of 1989 when Zhashui Agricultural Station of Zhangdian District, Zibo City, Shandong Province was popularized and applied more than 280 hectares . The benefits of sowing with dry-field wheat water and sowing: Firstly, it creates good soil moisture, ensures the whole plantation of wheat and makes full use of pre-winter precipitation, light and temperature resources to cultivate strong seedlings and good plant development. Second, increase the yield, significant benefit. Sowing wheat with a modified dry-field wheat-water crop yields 3,000 to 3,750 kg per hectare with the highest reaching 4,500 kg, an average of 81% more than dry-sowing at the same time and 45-75 kg of wheat per hectare, Income 579 yuan, significant economic and social benefits.
