同心县下马关公社下源大队科学试验小组,1973年试种了2.3亩杂交高梁,虽遭一百多天大旱的严重威胁,其它粮食近乎处于绝收状况下,但杂交高粱仍获得了平均亩产603.5斤的较好收成。其主要栽培经验概括起来,有以下几个方面:(1)抓苗:种杂交高粱的田块前茬为旱烟,地力中等偏下,上年秋天翻犁平整后灌足冬水,为适期播种创造了条件。据第三生产队的经验,采用耧播的办法出苗率比用木犁撒种的高。(2)蹲苗:为促使根系健壮生
Commune County Xiamaguan commune under the source of the brigade scientific experiment group, in 1973 planted 2.3 acres of hybrid sorghum, although more than 100 days of severe drought threat, almost all other crops in the state of harvest, but the hybrid sorghum is still getting an average of mu Produce 603.5 pounds of better harvest. The main cultivation experience summed up in the following areas: (1) Grab the seedlings: cross-sorghum field before the crop as a dry tobacco, soil fertility moderate lower than the previous fall tilled plowing winter irrigation water, for the appropriate period Sowing creates the conditions. According to the experience of the third production team, the use of broadcast method of emergence than wood plow sowing high. (2) Dunmiao: In order to promote a healthy root system
