Spring should be supplemented with potassium fertilizer in spring

Since the spring action of soil testing and formula fertilization, the soil and fertilizer experts of the Chinese Academy of Agricultural Sciences have taken active actions to penetrate the fields and guide scientific fertilization. Recently, experts from the Chinese Academy of Agricultural Sciences went to Hebei Yucheng to follow up on the growth of wheat. The survey found that due to the low ground temperature in spring this year, winter wheat greening in this area was delayed by 10 days compared with previous years. The first section of wheat was older than the first section, while the second section was not long and the stems were soft. Winter wheat has 12-16 knots, and the second quarter is the key. The technicians worry that if this happens, it will cause a large area of ​​wheat to fall in the face of dry and hot weather in June, which will seriously affect the yield and quality of wheat.
According to further investigations by experts, this phenomenon is more common in Hebei Yucheng. It is suggested that the majority of farmers in the winter wheat area should pay great attention. If urgent measures are taken within a week, this problem can be alleviated.
Experts put forward specific measures: spraying 30 kg of 1% potassium nitrate solution on wheat foliar surface, and spraying again after 3-5 days after the first spraying, the effect is better. The direct cost of spraying potassium nitrate is about 1 yuan/mu, with less investment and remarkable effect. At present, the agricultural administrative department of Hebei Lucheng City and the agricultural technology promotion unit have taken action to inform the farmers to spray potash fertilizer according to the advice of soil and fertilizer experts.
Experts have suggested the following problems for the growth of low-temperature wheat in spring this year. The following recommendations are recommended for farmers to plant winter wheat in the future: in the past, potassium fertilizer for one-time application of base fertilizer can be used for half-time application of wheat from the late stage to the early stage of jointing. It can replace paclobutrazol (a hormone), etc., and ensure the nitrogen and potassium needs of wheat during this time.

Rabbit Cage  has the advantages of convenient material extraction and economical application. Lath straight, firm and not hard, more resistant to bite bite, water absorption is small, easy to dry, good insulation, easy to nail. When the production should be bamboo file flat, edge without burr, nail head is not exposed. Lath width is generally 2.5-3cm. Its disadvantages are: sometimes the feces attached, thorough cleaning, disinfection is more difficult. If the quality of the slab is not good (such as strength is not enough) or the nail is not good (such as the width of the slab is different), it is easy to cause the fracture of the leg. Especially when it is easy to breed.
