How to skillfully manage late-season wheat? These technical points must be mastered
Ensure sufficient soil moisture and base fertilizer. For late-season wheat, never rush to sow by seizing moisture; on the premise of ensuring adequate soil moisture, apply heavy base fertilizer, and where conditions permit, apply 3-5 cubic meters of high-quality farmyard manure per mu; at the same time, according to yield requirements, mix 2/3 of the total nitrogen, phosphorus and potassium chemical fertilizers invested throughout the growth period with farmyard manure, spread them on the surface and plow them into the soil. Choose the right variety and increase the seeding rate. Late-season wheat is suitable for semi-winter varieties, which can be selected according to local conditions. At the same time, determine the actual number of days of late sowing according to local autumn temperatures. Generally, it is advisable to increase the seeding rate by 0.5 kg for each day of delayed sowing, and never

Earthing up ginger requires attention to technique; master the skills for a steady high yield
Earthing up is an important measure that determines ginger yield and quality. Only with proper earthing up can ginger grow vigorously and yield high. The rhizome of ginger needs to grow in a dark, moist environment, and stops growing when exposed to light. Therefore, earthing up should be carried out as the ginger grows. If earthing up is not done in time, the ginger rhizome becomes exposed to the air, which seriously affects ginger quality and yield. What methods should be mastered for earthing up ginger? How should earthing up be carried out to better promote rhizome expansion and increase yield? Li

Master the Three Earlies and Three Skills for Spring Potato Planting to Achieve High Returns
Three Earlies: Choose early-maturing varieties. Practice has proven that selecting high-yielding, high-quality, virus-free potato varieties with a growth period within 70 days (from emergence to harvest) is the key to achieving high, stable yields and quality in spring-planted potatoes. Currently ideal varieties include Holland No. 7, Holland No. 15, Zhengshu No. 6, etc. Start sprouting early. Using a sunny cold frame before planting to pre-sprout can make potatoes emerge early and uniformly, with complete and strong seedlings, promoting early plant development and early tuber formation - this is an important yield-increasing measure. The key points of sprouting technique are: before planting

How effective is the Jiaduo frequency-vibration insect-killing lamp at trapping and killing the rice stem borer?
The rice stem borer is one of the important pests in rice production in Wuchang City. In recent years, with changes in rice varieties and warming climate conditions in our city, the occurrence and damage of the rice stem borer have become increasingly serious. According to this autumn's survey, for certain varieties in Wuchang, the average number of insects per 100 steps per mu reached more than 20,000, with the highest in key outbreak areas reaching 60,000, and in some cases more than 100,000. Such insect numbers are rare in history, whether domestically or abroad. In order to further control the damage of the rice stem borer, explore new approaches to its control, and reduce pesticide pollution of rice. This year our city set up at Sun Guanghao's field in Lianhua Village, Wuchang Town
