No-till Wheat High Yield Cultivation Technique

No-till wheat, also known as rice buckwheat in our province. Compared to plowing wheat, no-till wheat has the following advantages:

1, the provincial labor saving section. No-tillage wheat employs 10.5 workers per mu, which saves 4 workers compared to cultivating plough wheat and reduces production costs.

2, No-tillage wheat does not misuse agriculture, rush to season sowing, make full use of the light and temperature resources during the year, lay a good foundation for the seedlings.

3, no-tillage wheat does not indiscriminate soil layer, fertilizer and soil in the topsoil, soil water, gas, and heat in the early growth period is better than ploughing wheat, which is favorable for seedling growth, promote early tillering, increase the number of low tillers, improve the rate of spike formation, It is beneficial to increase the number of effective panicles and increase production.

Second, no-till wheat high-yield cultivation techniques

1. Select high-yield and disease-resistant varieties. In North Zhejiang, Yangmai 158 and Yangmai 12 varieties were selected, and Wenmai 10 and other varieties were selected in Zhejiang and southern Zhejiang.

2, appropriate enough time sowing. The water is cut off 7 days before the rice is harvested to ensure that the soil after the late rice harvest is sufficient to create conditions for timely planting of the wheat. After harvesting the late rice Qi mud, cut high and fill in the ground to straighten the field surface. In northern Zhejiang, the seeds are planted from late October to early November; wheat is planted in mid-and-mid-November in central and southern Zhejiang. When appropriate sowing of wheat, the sowing rate per acre is 7.5 ~ 10kg, if the late sowing is appropriate to increase the amount of seed. Sowing should be uniform to prevent the emergence of clumps, while at the same time to be evenly spread to the edge.

3, timely ditch coverage. After the sowing of wheat, it should be covered in time. Advocate mechanical trenching, the general trench 2m, trench width 20cm, trench depth 20cm, try to improve land utilization. Gully to be evenly covered in the gutter surface, cover the thickness of 2cm, eliminate the dew. Do a good job in the field "three channels" (gutter, waist ditch, Tianbian ditch) matching, gully groove to reach the rain to ditch dry.

4, straw returned. The return of straw to the field has the function of protecting the weeds, inhibiting weeds, and increasing the organic matter of the soil, which is beneficial to increasing the yield of wheat and avoiding the environmental pollution caused by burning. Coverage of wheat after sowing can be covered before wintering, evenly cover 300kg of straw per acre, with grass not piles, field is not suitable for dew.

5, chemical weeding

(1) Killing rice field weeds before sowing. 2 days before sowing, 10% glyphosate 300ml or 20% grams per acre 100ml, watering 40kg spraying, blocking weeds in rice fields.

(2) Chemical weeding at the seedling stage. Weed 2 leaves 1 before the heart period, per acre with 50% isopropenol 150 grams or 6.9% of the gel 30mg gelding suspension, watered 40kg uniform spray for control.

6, scientific fertilization. The yield per mu of 250-350kg is 11-13kg of pure nitrogen, 5-6kg of phosphorus pentoxide, 4-6kg of potassium oxide, and 1000kg of high-quality farmyard fertilizer. Organic fertilizer, phosphate fertilizer, and potash fertilizer are all used as base fertilizers. 60% of the total amount of nitrogen fertilizer is used as base fertilizer, 10%-15% is used as seedling fertilizer, and 25-30% is used as panicle fertilizer.

7, control of pests and diseases. In the wheat flowering stage, 70% thiophanate-methyl WP 100g or 50% carbendazim WP 80g per mu was sprayed to prevent Fusarium head blight. When 100 strains of maggots reach 800-1000 heads, they are sprayed with 10% imidacloprid WP 20g and 30kg per acre.
