Prevention and control of wheat soil-borne diseases

The soil-borne diseases of wheat mainly include wheat root rot, wheat sheath blight and wheat total etch. Because its pathogenesis is mainly concentrated in the roots and stem bases, it is relatively concealed, and the pathogens harm the underground part. The symptoms are reflected in the aboveground part. The symptoms of mild diseases in the seedling stage are not obvious. In severe cases, the seedlings appear dwarf, the leaves are light, and the bottom leaves are yellow. Like the lack of fertilizer and other symptoms, the people are not easy to detect, when the emergence of "white spikes" in the later period, this has brought certain difficulties to prevention and control. I have tried many times to summarize a set of methods to control the three diseases of wheat. :
Dressing with pesticides. The chemical dressing is simple and practical, easy to operate, good in effect and safe. The specific method is as follows: the whole etched disease of wheat is treated with 12.5% ​​of total etched net 20 ml, and the heavily ill field is used up to 30 ml. 20 ml of water to 500 ml of seed dressing, mix well and mix well with 10 kg of wheat seeds, mix well and simmer for 6 hours before seeding. Control wheat root rot and sheath blight. Use 25% powder rust WP to seed dressing at 0.1% of seed amount or 50% carbendazim at 0.2%-0.3% seed amount. Can be sown.
Strengthen cultivation management to promote healthy wheat growth. Use reasonable fertilizer and water measures, apply more base fertilizer, play the role of organic fertilizer to prevent disease, and the manure with diseased body should be fully decomposed. Rational application of chemical fertilizers, avoid excessive application of nitrogen fertilizer, increase the application of phosphorus and potassium fertilizer. Wheat root rot occurs in a serious plot, paying attention to zinc supplementation. Pay attention to the ventilation and light transmission in the field, avoid the dampness and shade, and create the conditions for the development of unfavorable diseases.
Early spring prevention. Wheat tiller, jointing period with 50% carbendazim WP 300-500 times or 15% powder rust WP 80-100 grams of water 50 kg unplug the nozzle root.

Stainless Steel Sliding Door

Characteristics and Advantages

(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;

(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.

(3) Anti-clamping function: automatically reverse when meeting barriers;

(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)

(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;

(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;

(7) Bi-doors inter-locking: one of the door leaves always remains closing;

(8)Safety sensor terminal: sensor stops working when door closed;

(9)Unique coating technology: never rusty;

(10)Easy and convenient to install;

(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Details:

(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;

(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;

(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.

(4)Feet sensor switch applied to avoid contagion;
