为了获得丰产,如何进行密植?从今年各地小麦丰产实例中可以看出,密植是获得丰产的主要关键之一,凡亩产千斤以上的小麦,播种量多半在30斤以上。今年水稻插秧由原计划2—8万墩跃进到5万墩以上,甚至有插到10万墩的。今年小麦播种计划中,也有“万斤产量百斤种子”的说法。有的计划播种量达到170斤,这样密植法是否妥当?在高度密植情况下,应该用那些综合措施才能配合?密植到什么程度最合适?(山东广北农场王家祥)
In order to obtain high yield, how to carry out close planting? From the examples of high-yield wheat around this year, it can be seen that close planting is one of the key points for obtaining high yield. Whenever more than one kilogram of mu of wheat is produced, the seeding rate is above 30 kg. This year rice transplanting from the original plan 2-8 million pier jump to more than 50,000 pier, and even plugged into the 100,000 pier. In this year’s wheat planting plan, there is also a saying that “the output of a hundred pounds of catty catches a hundred pounds.” Some plans to sow the amount of 170 pounds, so close planting method is appropriate? In the case of a high degree of density, should use those comprehensive measures to tie? Close to what extent the most suitable? (Shandong Guangbei Farm Wang Jiaxiang)
