Experience of Late Harvest and Yield Increase in Maize Planting
The technology of late harvest and yield increase of maize is to fully prolong the filling time of corn, increase grain weight, increase maize yield and improve maize varieties without affecting the timely sowing of wheat. At the same time, if the land for the next crop must be harvested early, the connecting rod can be harvested and placed on the edge of the ground for 1 or 2 weeks before paying homage to the ear, which can promote the transfer of nutrients in the corn straw to the grain and significantly improve the yield and quality.
Technical points:
The main results are as follows: 1. Change the habit of harvesting when the bracts turn yellow, strictly grasp the signs of complete maturity of corn, that is, the grain hardens, the grain filling line moves down to the base of the grain and disappears completely, and the black layer at the base of the grain is formed. the grain presents the inherent color and characteristics of the variety, and the ear bracts become dry, fluffy and white.
2. the harvest was postponed for 10 days, and the harvest of corn was changed from 40 to 45 days after pollination to about 55 days after pollination. Make full use of the climatic resources in the late growth stage of corn, which are crisp in autumn and conducive to dry matter accumulation, prolong the filling time of corn as far as possible, and give full play to the potential of corn grain weight.
3. Accurately grasp the date of full maturity of local corn and actively promote mechanical harvesting. The sowing time of corn in our county is generally from late May to the first and middle of June, and the harvest time is generally at the end of September and the beginning of September.

Control of trematodes by spraying soil at booting stage of growing wheat
Wheat midge overwinters as mature larvae in deep soil with round cocoons and can be dormant for many years. When the soil temperature of 10 cm rises to about 7 ℃ in spring, that is, wheat begins to break its cocoon and move to the soil surface at jointing stage. In mid-April, wheat enters the booting stage, and the larvae enter the booting stage.
