High-yield Cultivation and Management of Wheat

In order to guide farmers in scientific farming, achieve high yield, high quality, and high yield in wheat, according to the laws of crop production, combined with the conditions of Wenshan, summarizing the working experience and the theory in connection with reality, we now provide reference to the farmers who like to cultivate wheat with high quality and high yield supporting cultivation techniques for wheat. :

1. Select good varieties: Use good quality, high yield per plant, strong resistance, high economic coefficient, and no premature aging, which will help achieve a production target of more than jin.

2, fine soil preparation, balanced fertilization: fine soil preparation to improve the structure of the soil, enhance soil water storage capacity, before sowing intensive cultivation, plowing 23-25cm, returning the stalks to the field, not only enhance soil fertility, but also to break Plow the bottom layer to reach the standard of deep, fine, transparent, flat, solid, and full (water), that is, the cultivating layer should be deep (20-25cm in dry land, 15-20cm in rice field), and the hoe should be fine (crushed) and thoroughly plowed after ploughing. , leveling, practical, to achieve the Panasonic real, water security. Do the construction of the trenches and build a facility for wheat field irrigation and drainage, and dig well the "three channels" (Yingou, Yaogou, and Yuantougou). After the spring, clear the "three channels" so that the ditch can communicate with each other to meet Irrigation and drainage requirements. Balanced fertilization Based on the comprehensive soil fertility status, a fertilization scheme was established. Organic fertilizers were mainly used, and organic and inorganic fertilizers were applied in combination to improve the organic matter content in the soil so as to achieve balanced fertilization. In order to avoid premature defertilization of wheat in the middle and late stages, about 50% of the nitrogen fertilizer was moved to the jointing stage until the booting stage, so that the content of lysine and protein in the wheat grain increased.

3. Appropriate amount of appropriate sowing: Seed treatment before sowing seed dressing or direct selection of coated seeds. In order to cultivate strong seedlings and form a wheat production group with a strong root system and a large number of stems and pods, it is necessary to sow seedlings in sufficient time to make full use of the caloric resources and lay the foundation for the high yield of wheat. Generally, wheat is most beneficial to emergence when its water holding capacity in the field is 70% to 80%. Therefore, when the sowing date and the soil moisture content conflict, it is necessary to make proper planting, and it can be planted 3 to 5 days late so that the whole wheat can be seeded. Seeding rate Determine the seeding rate of wheat according to the characteristics of wheat varieties and the sowing date. Usually the semi-winter and weak winter varieties are sown at the mid-to-late October and the end of September respectively. The seeding rate is 25 to 50 kg/hm2, which increases as the sowing date delays. The amount of broadcast. The end of September sowing in early October can be left to 1.5 million 1.8 million / hm2. For large spike-type cultivars with low tillering and spike formation, the appropriate basic seedlings were 1.95 million to 2.7 million plants/hm2.

4, scientific field management: scientific fertilization and weed control in order to prevent the occurrence of lack of seedlings off ridge phenomenon, to ensure safe winter wheat, we must promptly irrigation, so that the formation of strong wheat. Chemical regulation Anti-lodging Wheat lodging is divided into two kinds of root lodging and stem lodging, which is mainly stem lodging, mainly due to the large amount of nitrogen fertilizer in the early stage, resulting in large wheat groups, closed fields, poor ventilation, and light wheat. Prosperous, the internodes of the base are too long, and wheat is prone to lodging under strong winds in the late days. Therefore, in wheat production, scientific fertilization should be based on soil fertility. Earing and grain-filling at the ripening stage of wheat heading and flowering (in mid-April and late April) to prevent and control wheat aphids, midgeworms, armyworm, rust, powdery mildew, and erythrodermic diseases, prolong the growth period of wheat, increase yield, and spray insecticides. Agent, continuous use 1? 2 times. At the same time, irrigation 1?2 times, the first irrigation in the first spike flowering period, to increase grain growth and promote grouting, to achieve grain size, grain weight, prevent premature root failure; the second irrigation wheat yellow water to supplement Moisture, and preparation for the re-broadcasting of the second crop.

5, timely harvest: generally in mid-June, the basic maturation of wheat in the middle of the entire wheat field 2/3 when the yellow wheat harvest, wheat wax maturing is the best harvest. However, wheat should not be too mature to prevent grain loss and reduce yield.
