Wheat sowing is late, so broadcast it! After reading this, I will not cut production next year!

According to the forecast of the Central Meteorological Observatory on October 18th, it is expected that in the next week, most of the northern period will be dominated by fine weather, which will help the autumn crops mature and harvest; the soils in the northwestern part of the country, North China, Huanghuai and other places will be suitable for timely planting of winter wheat.

For the North China and Huanghuai wheat areas, wheat planting has been delayed due to continuous rainy weather. Agricultural experts pointed out that the current "cold dew" has passed, just as the wheat is suitable for sowing period, we must earnestly do a good job in wheat planting, and adopt the following technical measures to ensure a bumper harvest and food security for summer crops next year.

First, we must speed up the autumn harvest and the speed of the tide. It is necessary to seize the gap in the precipitation, harvest and vacate in time, and strive to harvest one piece and make a piece of it to gain time for timely planting of wheat. For harvested crops, it is necessary to take care of air drying or mechanical drying to prevent mildew, ensure quality, and return the grain.

Second, we must adapt to local conditions and rush to sow. At present, due to the high humidity in the field, agricultural machinery can not work in the ground. In order not to mistake the farming, the land preparation method should be simplified, the land preparation time should be shortened, the land preparation progress should be accelerated, and wheat should be robbed. For soybeans, peanuts, peppers, etc., no-tillage can be adopted. Live broadcast, live broadcast after squatting or sowing after rotary tillage; for corn glutinous rice, it is necessary to use fine weather, timely smashing the land to make a good piece, sowing a piece; soil over wet land, pay attention to timely clearing the ditch after rain, prevent The farmland is getting too wet.

Third, we must emphasize shallow broadcasting. Due to continuous rainfall, the field holds a large amount of water, the ground temperature is low, and the ventilation is poor. It should be as shallow as possible, and the sowing depth should not exceed 3 cm, in order to facilitate early emergence and shorten the emergence period. Avoid deep sowing to prevent deep sowing of weak seedlings.

Fourth, according to the sowing date, the amount of broadcast should be appropriately increased. Due to the influence of the rain, the sowing date is postponed and the sowing amount should be increased appropriately. In principle, the amount of sowing in the area around 15 October is about 15 kg; the amount of sowing in October 25-31 is 15-18 kg; the amount of sowing in November 1-10 is 20 About kilograms; after sowing in November 10, the amount of sowing is not less than 22.5 kg. (taking Xuchang area as an example)

The fifth is to change the variety at the right time. After the broadcast period is after October 25, if possible, use weak spring varieties as much as possible. The weak spring wheat varieties suitable for planting in Xuchang City are: Xi Nong 529, 04 Zhong 36, Lankao 198, Qumai 18, Zhongmai 7, Zhengmai 9023, Zhengmai 113, Zhengmai 119, Huaichuan 919, etc.; Strong gluten and weak spring varieties include Xi Nong 529, Xi Nong 509 and Huai Mai 30. (Other areas can consult the local agricultural sector)

Luohe City: Agricultural experts suggest that it is necessary to promptly eliminate water in the field, select wheat varieties, and plant winter wheat according to its characteristics. In the selection of varieties, it is necessary to use semi-winter varieties, and appropriately match weak spring varieties. High-quality wheat focuses on the development of medium-strength varieties. Among them, the sowing season of semi-winter varieties is from October 10 to 20, and the weak spring varieties are from October 15 to 25.

The agricultural experts especially reminded the farmers that the wheat sowing period is a favorable period for the prevention and control of pests and diseases. According to the type and degree of the occurrence of pests and diseases, the right medicines should be used to do the seed coating, the chemical dressing and the soil treatment. For a variety of pest and disease mixed areas, the use of fungicides and insecticides in various amounts of mixed seed dressing or seed coating, in order to achieve "a mixture of multi-effect."

For wheat all-invasive disease, sheath blight, root rot, smut and other soil-borne, seed-borne diseases and underground pest control, wheat special coating agent can be used for seed coating, but tebuconazole can also be used. High-efficiency agents such as difenoconazole and flavonol are used for seed dressing.

Can refer to the following method: 30 g / liter of difenotropium suspension seed coating agent (Centre) 20-50 ml water 100-150 grams, mixed wheat seeds 10-15 kg; In the hair-producing area, use 1 bag of 12.5% ​​thiabendamine suspension agent (20 ml) to water 150-250 g, mix 10-12.5 kg of wheat seeds, mix well and simmer for 6-12 hours, dry in a cool place. sowing.

For the underground pest occurrence area, according to the occurrence of underground pests, a certain amount of insecticide can be added and mixed with the seed dressing. After the seeding, the piles are piled for 3 hours, and dried in the backyang and then sown. In the area where the underground pests are seriously affected, the combination of soil treatment and seed treatment should be used for prevention and treatment. The soil treatment can spread the ground evenly with 2-3 phoxim granules per acre of 2-2.5 kg, and then turn it into the soil.
