Six key management practices to focus on after transplanting spring eggplant in a large arch shed
I. Temperature control For spring eggplant cultivated in a large arch shed, from transplanting until the seedlings recover, the shed should be kept closed to retain heat, keeping the temperature inside the shed at 28°C-30°C during the day and 15°C-20°C at night as much as possible. After the seedlings recover, attention should be paid to ventilation, keeping the shed temperature at 23°C-25°C during the day, generally not exceeding 33°C. II. Fertilizer and water management Under conditions of good soil moisture, water as little as possible before the first eggplant reaches the size of a walnut, to raise soil temperature and prevent flower and fruit drop. When the first eggplant reaches the size of a chicken egg, apply 10 kg of urea per 667 sq m along with watering. After that, appropriately increase the frequency of watering according to soil moisture.

Causes of Spring Yellowing in Winter Onions and Control Methods
For some time now, the author has continuously received letters or phone calls from the public asking about spring management of winter onions. Some people report that winter onions which grew well under low-temperature conditions developed yellowing leaves, root aging, and even death after temperatures rose in early spring, and that cold-resistant winter onion seedlings actually grew worse than local winter onions. Why? Through field observation, the author learned that in spring 2005, winter onions in most regions nationwide showed similar conditions. On the Jiaodong Peninsula, which has the largest planting area in the country, many

Key Technical Points for Early Spring Field Management of Late-Sown Wheat
Because last year's wheat sowing period around the "National Day" (October 1) encountered heavy rainfall, wheat farmers did not sow until after the Cold Dew solar term, resulting in late wheat; in addition, the rainfall at that time also delayed the growth of wheat sown at the normal time, which also formed late wheat. As a result, more than half of the 1.1 million mu of wheat sown in this city last year was late wheat. The growth characteristics of late wheat differ from those of ordinary wheat, so the early spring management techniques are also different. Late wheat generally refers to wheat sown after the Cold Dew solar term. Its growth characteristics differ from those of wheat sown at the appropriate time, mainly shown as: overwintering seedlings

What are the common diseases of peppers in early spring? This article summarizes them for you
Recently, continuous cloudy, snowy and cooling weather has seriously affected the normal growth of chili peppers and sweet peppers. According to what the author learned on March 5 in pepper growing areas such as Jitai Town, Sunjiaji Subdistrict Office and Gucheng Yangjia Village in Shouguang City, chili peppers and sweet peppers currently in the fruiting stage are commonly infected due to the unfavorable weather, mainly with gray mold and sclerotinia disease --- brown water-soaked lesions appear at the top or stem end of young fruits, then become sunken and rot, and a gray mold layer appears on the surface of the lesions; sclerotinia disease spreads from the fruit stalk to the whole fruit, showing water-soaked rot, light grayish brown,

Key Management Measures After Planting Spring Eggplants in Polytunnels
1. Temperature control. For spring eggplants grown in large polytunnels, after the seedlings are planted and before they recover from transplanting, the tunnel should be kept closed to retain heat, keeping the temperature inside the tunnel at 28-30°C during the day and 15-20°C at night as much as possible. After the seedlings recover, attention should be paid to ventilation, keeping the tunnel temperature at 23-25°C during the day, generally not exceeding 33°C. 2. Fertilizer and water management. When soil moisture is good, water as little as possible before the first eggplant (the "door eggplant") reaches the size of a walnut, to raise soil temperature and prevent flower and fruit drop. When the door eggplant reaches the size of an egg, apply 10 kg of urea per mu along with watering. After that, appropriately increase the frequency of watering according to soil moisture conditions.
