At the same time, 150~187.5kg/hm2 ferrous sulfate was used for soil disinfection. Then turn it deep, remove the weeds in the ground and make a cockroach. As a low bed, sorghum, 畦 width 2m, length 1m, 埂 height 20cm.

The sowing method is strip, and the ditch is used to open a ditch of 1~1.5cm, the row spacing is 15cm, and the soil should be compacted after sowing. The seeding amount is 22.5kg/hm2. In order to ensure the sprouting rate, after planting for I~2d, the ground is somewhat Water when dry. When the seedlings began to emerge, weeds have appeared. At this time, weeding and cultivating should be carried out in time, and 90% of the trichlorfon 800 times liquid should be sprayed once, or the bait should be removed to prevent cockroaches and cockroaches.
