Detailed Explanation of Key Technical Points for Raising Muskmelon Seedlings in Early Spring
To prepare the nutrient soil, use fertile soil that has never been planted with melons or vegetables and fully fermented and decomposed chicken manure or human waste, sift and mix them thoroughly at a ratio of 7:3. For each cubic meter of nutrient soil, add 2.5 kg of superphosphate, 0.5 kg of potassium sulfate, and 15-20 g of 95% hymexazol. To build an electric heating hotbed, 24-26 sq m of seedbed is needed per mu of field. The seedbed is wide 1...

Soybean Disease Control Measures and Technical Key Points
Soybean Sclerotinia Stem Rot Soybean sclerotinia stem rot mainly infects the stems, and symptoms usually begin to appear in late July. In the early stage of infection, brown lesions appear on the stems, after which white cottony mycelium and white granules develop on the lesions, later turning into black granules (sclerotia). When the diseased plant stem is cut lengthwise, black cylindrical sclerotia resembling mouse droppings can be seen. After the diseased plant dies...

Detailed Explanation of the Key Technical Points for the "Three-Avoidance" Cultivation of Melons
Scientific fertilization. According to the fertilizer and water requirements during the melon's growth period, supply fertilizer and water in a balanced manner; do not irrigate or fertilize blindly. When fertilizing, not only should sufficient base fertilizer be applied to meet the needs of the melon's early growth, but also timely topdressing should be carried out in the later stage of melon growth to meet the fertilizer requirements of the melon's later growth. Reasonable irrigation...

Open-field sowing methods and technical key points for melons
Open-field melon sowing method: open-field melons are grown using plastic film mulching with a water-and-dry bed system. Generally, the water bed is 0.5 m wide, the dry bed is 1.5-1.8 m, and the furrow is 20 cm deep. A north-south orientation of the beds is best. Before forming the ridges, open a small furrow (8-10 cm) with a small plow on both sides of the dry bed at 30 cm from the ridge edge line and apply organic fertilizer. The ridge height is 20 cm, the top opening of the water furrow is about 50 cm wide, and the depth is...

Key Technical Points for High-Yield and High-Efficiency Cultivation of Thin-Skinned Melons in Cold Greenhouses
Thin-skinned melons have traditionally been cultivated by letting the vines trail on the ground, with the vines growing in a tangled and crisscrossing manner that is very difficult to manage, and the yield is also low. When thin-skinned melons are cultivated in cold greenhouses, using the trellising method just like growing cucumbers in large greenhouses, higher yields and economic benefits have been achieved, with an average of 667 sq m producing over 5,000 kg of melons, and a net benefit of...

How to prevent and control corn gray leaf spot? A full analysis of the technical key points
Corn gray leaf spot can occur throughout the entire growth period, but the disease is most severe at the tasseling and grain-filling stages. In the early stage of the disease, water-soaked light brown spots appear. These streaks extend parallel to the leaf veins, are often rectangular, and are more obvious when held up to the light. The center of the lesion is gray, and the edge has a brown line. The lesion size is 2-4 x 10-24 (mm), and...

Three-step early spring management for asparagus: technical points growers must see
Because asparagus prices have been low for the past two years, most asparagus growers have given up field management or intercropped other crops in asparagus fields, seriously affecting the growth, development and yield of asparagus. In addition, the snow disaster that occurred too early in 2009 froze the plants to death, resulting in less nutrient accumulation and a reduced number and differentiation of scale buds. If effective measures are not taken,...

Key Technical Points for Spring Field Management of Melons
Fertilization: Apply the base fertilizer all at once in sufficient quantity. Dig a furrow 30 cm from the plants, and apply 50-100 kg of potassium sulfate compound fertilizer per mu, or 2-3 cubic meters of decomposed livestock and poultry manure. Or apply 50-100 kg of ternary bio-organic fertilizer. In the middle and late stages, spray the leaves with potassium dihydrogen phosphate + 600-800 times dilution of Xin Gao Zhi Mo, and at the same time spray Cui Hua Wang No. 3 to balance vegetative growth...
