Summer topdressing methods and technical points for eggplant
Furrow application. Vegetable growers have become accustomed to applying chemical fertilizer by broadcasting it with irrigation water, but this method is not suitable during the hot summer season. Because the temperature is relatively high, when chemical fertilizer is applied with irrigation water, a large amount of ammonia volatilizes, which reduces the effect. This is especially true for ammonium bicarbonate, which is more likely to cause ammonia poisoning in eggplant. Applying it in furrows or burying it in holes gives the best results...

Detailed Explanation of Pollution-Free Cultivation Technical Regulations for Greenhouse Cucumbers
I. Soil Selection and Tillage 1. Soil selection: Choose a field with fertile soil, convenient transportation, and where the previous crop was not a cucurbit crop as the cultivation site. 2. Plowing, sun-bleaching and disinfection: The cultivation site should be flooded and plowed one month before planting, and after drying, land preparation should be carried out. 3. Bed preparation: 3-5 days before planting...

Detailed Explanation of Common Celery Seed-Saving Methods and Technical Points
In recent years, many regions have cultivated some high-quality common celery varieties, and they also account for a relatively large proportion in sowing. Because celery is a cross-pollinated crop, for common varieties it is especially important to do a good job in seed saving and preventing degeneration, to truly establish a good seed-saving field or seed-production site, and to select and retain good seed plants. Strictly isolate in the seed-saving...

How to overwinter and protect spinach seedlings in the north? Key technical points explained in detail
Celery, also known as Western celery, foreign celery, or American celery, is planted in autumn in the Shuyang area. The average yield per mu is 3000-4000 kg, and high-yielding fields can reach 5000 kg per mu. Its high-yield autumn cultivation techniques are briefly described as follows: 1. Select good varieties for sowing. Choose varieties that bolt late, have strong stress resistance, are not prone to softening, and have thick, solid stalks...

What are the technical measures for spinach sowing management?
After sowing spinach, fasten the greenhouse cover properly. Generally, two waterings are needed for full emergence; 10 days after emergence, water again. Once the two true leaves of spinach unfold, the leaf number, leaf weight, and leaf area increase rapidly. Before 3 to 4 leaves, keep the soil moist, apply 25 kg of ammonium bicarbonate per mu, shallow hoe once, thin out overly dense seedlings, and control water appropriately. In November around "Minor Snow"...

Key Technical Points for Pollution-Free Pest and Disease Control in Strawberries
Symptoms: Strawberry black mold mainly affects nearly ripe fruit. If harvested fruit is not promptly handled and packaged, it is even more susceptible to infection, causing large-scale fruit rot. When the disease first appears, the fruit surface shows light brown water-soaked lesions, which then rapidly soften and rot, producing a gray cotton-like growth, on which granular black mold develops, namely the mycelium and conidia...

Disease Prevention and Control Measures and Technical Key Points for Greenhouse Strawberries
Strawberry leaf blight mainly affects leaves, petioles, fruit stalks and calyxes. 1. Symptoms. In the early stage of the disease, small dull dark purplish-brown spots appear on the leaves, which then expand into irregular lesions; the color of the lesion edges and centers changes little, and the symptoms of this disease are difficult to distinguish from those of brown spot disease in its early stage. Brown spot disease and leaf blight...

How to overwinter and preserve autumn spinach seedlings? A full analysis of the key technical points
Autumn spinach is an overwintering vegetable sown in autumn and harvested in spring. It begins overwintering at the end of November and turns green again in early March of the following year, a period lasting more than 100 days. Therefore, under long-term low-temperature and dry conditions, how to ensure safe overwintering is the key to achieving a bumper harvest. 1. Water the freezing water well. Watering the freezing water must achieve "one determination" and "two suitability...

What are the technical key points for thinning male flowers and removing tendrils in loofah?
Reasonable thinning of male flowers and removal of tendrils in loofah can reduce unnecessary consumption of nutrients in the soil and within the plant, allowing nutrients to be concentrated for fruit growth and development, thereby increasing yield per unit area. Trials have shown that under otherwise identical cultivation and management conditions, compared with loofah without male flower thinning and tendril removal, loofah with male flower thinning and tendril removal increased the fruit-setting rate per plant by...
