Wheat head blight dataset

Wanmai 27, Wannian 2, Zhengyin 1, 2133, Ning8026, Ning8017, etc. Spring wheat has Dingfeng 3 and Ningchun 24. Local selection can be made according to local conditions.

[Agricultural control] Rational drainage and irrigation, wetland ditching and drainage. After harvesting, deep tillage should be carried out to eliminate stubble and reduce bacterial sources. Sow seeds in time to avoid rain during flowering season.

It advocates the application of compost made by fermentation bacteria, the use of formula fertilization technology, rational fertilization, avoiding partial application of nitrogen fertilizer, to improve plant disease resistance. [Drug control] 1. Seed dressing with yield-increasing bacteria.

Each 667 m ^ 2 was sprayed with 100 - 150 g of solid or 50 ml of liquid microbial agent. The seeds were mixed with water and dried before sowing. (2) Preventing ear rot in the flowering stage of wheat.

Spraying at the beginning of flowering stage should be used at the early stage of full heading and flowering (the rate of flowering plants is 5-10%). Pesticides with good permeability, rain erosion resistance and sustainability should be selected for pesticide control. 25% cyanobacterial ester suspension agent 100-200 ml per mu, 40% pentazole prochloraz water emulsion 20-25 ml, or 28% enoxime carbendazim wettable powder 50-95 g, sprayed with 30-45 kg of water mist.

Depending on the weather conditions, variety characteristics and growth period, spray the second medicine every 7 days or so, and pay attention to alternate medication. In addition, 667m ^ 2 had excellent control effect in the mixed area of scab, wheat aphid and armyworm in the middle and late stage of wheat growth with 40% chlorpyrifos 30ml or 10% aphid-resistant carb 10g plus 40% hekuling 100g or 60% fungicide 70g plus potassium dihydrogen phosphate 150g or urea and high yield urea.

In the middle and lower reaches of the Yangtze River, the spraying period is often rainy or rainy. It must be grabbed before the rain or when the rain clears the water. After spraying, it can be sprayed 1 times after 5~7 days, so as to improve the control effect.

When spraying, we should focus on the wheat panicles and spray evenly.
