High-Yield Cultivation Techniques for Greenhouse Peppers Across Spring, Summer, and Autumn
At present, the main problem in production is that early spring cropping dominates, while after the greenhouse film is removed in summer, autumn delayed production is relatively limited. After summer, as open-field vegetables reach the market, management is relaxed, and late-season pepper yields are relatively low. To maximize the production role of greenhouse facilities, the author guided farmers to carry out a single large cropping cycle of greenhouse peppers across spring, summer, and autumn...

How to fertilize peppers scientifically in spring? A detailed guide
Selecting good seeds: Winter-spring season cultivation is essentially early-maturing cultivation, so attention must be paid to the early maturity of the variety while also considering high yield and disease resistance. Suitable varieties include Hongyingda, Andale, Shengfangzhou, as well as Bulgarian hot pepper and Sujiao No. 5. Land preparation and fertilization: apply 10000 kg of high-quality manure or compost per mu as a base dressing, and apply urea in furrows...

Four cultivation models based mainly on spring radish and chili pepper
Winter-spring chili pepper is currently the most important production season for chili pepper cultivation in solar greenhouses. Generally planted in mid-November, it can be harvested and marketed in early January of the following year, continuing until the next summer. The main cultivation techniques are explained as follows: 1. Build a greenhouse. For new energy-saving solar greenhouses, the structure and environment of the original solar greenhouse...

Detailed Explanation of Key Points for Spring Cultivation Techniques of Napa Cabbage
Spring napa cabbage, summer napa cabbage, and early spring napa cabbage do not have a strict harvest period; they can be harvested once the heads have formed. Autumn-winter napa cabbage has a strict harvest period and must be harvested before a low temperature of -2°C occurs. After harvesting napa cabbage intended for storage, orient the heads facing north and the roots facing south, and sun-dry for 2-3 days. Then stack the plants into two rows, ...

How to manage spring early-maturing eggplant during the fruiting period? Practical technical key points
For eggplants grown in spring under plastic film low tunnel cover, from flowering to fruit harvest, under suitable conditions it takes about 18-25 days, and the initial harvest period of the first fruit (door eggplant) is in early to mid-May. During fruit growth, the weather has already turned warm, so the film can be fully uncovered during the day to give the plants plenty of light, but it must be covered well again in the evening. If the nighttime temperature...

Key Points of High-Yield Cultivation Techniques for Spring-Planted Cassava
1. Deep plowing to improve the soil. One month before planting cassava, plow the land first and let it dry white in the sun so the soil is fully weathered. At planting time, apply 250-300 kg per mu of phosphate fertilizer composted and rotted with poultry and livestock manure as a base fertilizer. 2. Select good varieties. Be sure to choose varieties that form many tubers, have low toxicity and give high yields. Also select stems from the middle and lower parts that are thick, have close nodes, and are free of pests, diseases and damage for use as seed stems.

Common Problems of Greenhouse Eggplant in Early Spring and Their Control Methods
In the early spring season, when temperatures are low and light is weak, greenhouse eggplant often shows various abnormal conditions. The common problems and their control are described below: 1. Stunted seedlings In the early spring crop, eggplant often shows stunted seedling symptoms at the seedling stage, such as small leaves, dark green color, thin stems and few roots. After transplanting, such seedlings recover slowly, grow weakly, and...

How to prevent and control seed rot after sowing spring peanuts
After sowing spring peanuts and before emergence, seed rot often occurs, with severe cases reaching a rot rate as high as 20%, causing missing plants and broken rows to varying degrees. Causes of seed rot: poor seed quality or improper storage, or too long a storage period; low-lying terrain, heavy clay soil, poor texture, and high soil water content, resulting in a long emergence time for seeds; poorly consolidated seedbed preparation, which affects the...

High-yield technique for large-scale film-mulched spring peanut sowing with pod sowing, moisture borrowing and dry sowing
Pod sowing with film mulching is an effective measure for early sowing of spring peanuts by borrowing soil moisture, ensuring full stands, resisting drought and increasing yield. The Agricultural Technology Extension Center of Linmu County began trials and demonstrations in 1987, and from 1992 to 1993 the implemented area reached 8,520 hectares, with average unit yields reaching 3,982.5 kg/ha and 4,057.5 kg/ha, increases of 13.9% and 16....

Eight Precautions for Film-Mulched Cultivation of Spring Peanuts
Applying film-mulching cultivation technology to peanut production can raise temperature, ensure full stands, retain water and preserve fertilizer, thereby achieving increased yield, higher income and giving a head start on the season. In 2002, our institute conducted a comparative trial of film-mulched cultivation of spring peanuts, obtaining a plot trial yield of 402.75 kg per mu and a field yield of 367....
