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.

Xenon Arc Lamp Aging Test Chamber

A Xenon Arc Lamp Aging Test Chamber is a specialized testing equipment used to simulate the aging effects of sunlight on various materials and products. It is commonly used in industries such as automotive, aerospace, and textiles to evaluate the durability and performance of materials under prolonged exposure to sunlight.

The chamber consists of a xenon arc lamp, which emits a broad spectrum of light similar to sunlight, and a sample holder where the materials or products to be tested are placed. The lamp emits high-intensity light, including ultraviolet (UV), visible, and infrared (IR) radiation, which can be adjusted to simulate different weather conditions and intensities of sunlight.

The test chamber is designed to control various parameters such as temperature, humidity, and light intensity to accurately replicate real-world conditions. It can simulate different weather conditions, such as sunlight, rain, and humidity, to assess the effects of these conditions on the materials being tested.

By subjecting materials to prolonged exposure in the Xenon Arc Lamp Aging Test Chamber, manufacturers can evaluate the effects of sunlight on color fading, material degradation, cracking, peeling, and other forms of deterioration. This information helps them make informed decisions about the selection of materials and determine the expected lifespan of their products.

Overall, the Xenon Arc Lamp Aging Test Chamber is an essential tool for quality control and product development in industries where prolonged exposure to sunlight can impact the performance and durability of materials and products.
