How to plant spring peanuts at a reasonable density? Key technical points on planting density
To achieve high yields of spring peanuts, six technical steps must be mastered: 1. Select excellent varieties. Good seed is the foundation for high yields, so varieties with strong resistance, high yield and high oil content should be used first. In recent years, trials have shown that "three-high" good varieties such as Shanyou 523, Shanyou 71, Yueyou 79, Guihua 21 and Wuyou No. 7. When planting, also...

Key Technical Points for Top Grafting and Replacing Varieties by Sawing Off Trunks of Old Bayberry Trees
I. Cultivating Vigorous Rootstock 1. Deep plowing and fertilization. In late autumn, deep plow the entire orchard to 20 cm, and apply per tree 15 kg of farmyard manure + 0.25 kg of urea + 0.5 kg of calcium magnesium phosphate fertilizer + 0.25 kg of potassium sulfate. Spread 25 kg of lime per mu to neutralize soil acidity and promote root absorption. 2. Saw off trunks at the right time to promote rootstock sprouting. ...

Key Technical Points for Raising Seedlings of Pumpkin in Solar Greenhouses with Vertical Trellis Cultivation for the Winter-Spring Crop
①Determining the sowing date The sowing date is mainly determined by the heat retention of the solar greenhouse. A solar greenhouse with good light transmission and good heat retention can be sown and raised as seedlings in late November. The melons are harvested in mid-March of the following year. Otherwise, the sowing date can be postponed to January of the following year. With the above-mentioned solar greenhouse, sowing and seedling raising are generally carried out from late December to early January of the following year...

What are the technical measures for soybean pest and disease control
Soybean cyst nematode disease, commonly known as "fire dragon seedling," is a soil-borne, devastating soybean disease. The western part of our province is a severely affected area of this disease. In mild cases, yield is reduced by about 10%; in severe years, yield can be reduced by 30%-50%, and in serious cases, there may even be total crop failure. Soybean cyst nematode mainly damages soybean roots. Affected plants are stunted and poorly developed, and at the seedling stage are susceptible...

Detailed Explanation of Key Technical Points for Fruiting Management of the Shaggy Mane Mushroom
The relative air humidity inside the shed should be maintained at 85-90%; if too high, the fruiting bodies are prone to discoloration or brown blotches. If too low, the fruiting bodies are prone to curling back their scales prematurely; the temperature inside the shed should be kept at 16-24 degrees to favor the highest fruiting body formation and the highest yield; ventilate 1-2 times per day, for 30-40 minutes each time; after harvesting the mushrooms, fill the mushroom pits level, and the harvesting standard...

Key Technical Points and Methods for Applying Molybdenum Fertilizer to Soybeans
Molybdenum is a trace element essential for nitrogen metabolism in crops, and especially essential for the process by which nitrogen-fixing bacteria fix atmospheric nitrogen, so the effect of applying molybdenum fertilizer to legume crops is consistent. Xiao County has about 300,000 mu of soybeans planted year-round, and according to tests by the Suzhou City Soil and Fertilizer Station, 95% of the soil in Xiao County is deficient in molybdenum. In response to this situation, the Xiao County Soil and Fertilizer Station...

Methods and Key Technical Points for Pest and Disease Control in Oil Beans
Main symptoms: Beans can be infected by pathogens throughout the entire growth period, but resistance weakens and susceptibility increases from the beginning of flowering to the fruiting stage. The disease mainly attacks leaves. In the early stage of the disease, chlorotic yellowish-white spots appear on the leaves, and the spots gradually increase until they densely cover the entire leaf. Plants are stunted, pods are few and small, and the growth period is shortened...

Technical Key Points for Cultivating Coprinus comatus (Shaggy Mane Mushroom) with Biogas Residue
1. Substrate formula: 300 kg biogas residue, 200 kg corncobs, 10 kg superphosphate, 1.5 kg urea, 20 kg lime powder, 5 kg gypsum powder, 5 bags of Mushroom Disease Eliminator, and 240 g of the three-dimensional edible mushroom nutrient essence. 2. Substrate composting: Except for the three-dimensional nutrient essence, mix the corncobs directly with fresh biogas residue and auxiliary materials...
