移栽高粱是广大群众在生产实践中创造出来的一种好办法。它不但能够争取时间充分利用土地,节约种子,避过春忙,合理调配劳力,而且有利于植株蹲苗,使高粱生长健壮,夺取高产。尤其是油菜田,人们更喜欢搞移栽高粱。我省晋中一带收获油菜在6月初,这时直播高粱苗高1.2尺左右,正好移栽。采取这一措施,可使油菜、高粱生产两不误。但近年来高粱丝黑穗病普遍发生,为害严重。在这种情况下,移栽的高粱比直播高粱发病更重,减产幅度更大。人们开始认识到在重病区搞移栽高粱弊多利少,得不偿失。据在平遥县马壁大队调查,1976年以前,高粱丝黑穗病发生很轻,直播田发病率一般为2—3%,移栽田发病率为6—7%;1977年直播田发病10—20%,移栽田
Transplanting sorghum is a good way for the masses to create in production practice. It can not only strive to make full use of the land for time, save seeds, avoid spring rush, and rationally deploy labor, but also help plants to grow seedlings and make the sorghum grow robust and seize high yield. Especially rape fields, people prefer to engage in transplanting sorghum. Jinzhong area harvest rapeseed early in June, when the direct seeding height of about 1.2 feet sorghum, just transplanted. Take this measure can make both rape and sorghum production correct. However, in recent years, sorghum head smut is widespread and serious damage. Under such circumstances, the transplanted sorghum is more serious than the direct seeding sorghum and the yield reduction is even greater. People began to realize that it is more harm than good to use less sorghum in the seriously ward area. According to the investigation of the Pingtung County Mabi team, prior to 1976, there was very little sorghum smut. The incidence of direct seeding was 2-3% and the incidence of transplanting was 6-7%. In 1977, the incidence of direct seeding was 10 -20%, transplanting field
