Technical Service Information for Tea Plant Frost Resistance and Post-Disaster Recovery
I. Remedial measures for tea plants after a disaster: 1. Scientific pruning: Because tea gardens with different varieties, different altitudes, and different slope aspects have different degrees of frost damage to their tea plants, generally tea gardens with large-leaf varieties, high altitude, and north-facing slopes suffer more severe frost damage to the tea plants. Timely and reasonable pruning should be carried out according to the degree of frost damage. After the temperature rises and stabilizes, observe the frost damage to the tea plants. For lighter frost damage, use light pruning, that is, cut about 3 cm below the leaf surface. For more severe frost damage, carry out deep pruning, cutting off 1/2-1/3 of the plant. For particularly severe frost damage

How to mix nutritional formulas for silkworms in summer and autumn
The main feed for silkworms is mulberry leaves. Since the quality of mulberry leaves varies greatly between seasons, it has a considerable impact on cocoon yield and quality. If nutritional supplements are fed to silkworms raised in summer and autumn, the yield can increase by 10%-20%. The formula techniques are introduced as follows: 1. Supplement formulas and feeding methods. 1. Glucose solution additive. During the silkworm rearing period, if there is continuous rainy weather, the mulberry leaves are tender in texture due to insufficient sunlight, have a high moisture content, and lower carbohydrates. At this time, a 5% glucose solution can be sprayed on the harvested mulberry leaves. After

High-nutrition formula cultivation of oyster mushrooms can achieve exceptionally high yields
The high-nutrition, exceptionally high-yield cultivation technique for oyster mushrooms uses raw materials such as wheat straw and rice straw, and adopts measures including high-nutrition formulas, removing the plastic casing from the mushroom logs, and covering with nutrient soil, so that the input-to-output ratio reaches more than 1:10, with very significant economic benefits. 1. Strain selection: choose wide-temperature varieties such as Changbai No. 1. The suitable cultivation time is from September of the current year to April of the following year. 2. Formula and treatment: there are 4 formulas: ① 50% soybean straw (crushed), 40% corncob or wheat straw, 8% cornmeal or wheat bran, 2% lime. ② 70% wheat straw, 27% wheat bran, 1% compound fertilizer

Performance of Top-Grafted Hongnanguo Pear Introduction and Key Cultivation Techniques
Hongnanguo pear is a bud sport of Nanguo pear identified in 1996 at Shenyang Agricultural University. In 2003, Luan County introduced 5000 scions from the Fushun Special Products Research Institute for top-grafting trial planting. It performed well in Luan County. In the second year after top-grafting, the yield was 300 kg per 667 sq m with an income of 4200 yuan; in 2005, the yield was 800 kg per 667 sq m with an income of 8000 yuan; in 2006, it reached 1500 kg with an income of 12000 yuan, showing significant economic benefits. 1 Basic Information of the Top-Grafting Trial Orchard The introduction site was set up in

Causes and Control Methods of Deformed Oyster Mushrooms
Deformed mushrooms are a relatively common physiological disorder in oyster mushroom production, severely affecting the yield and quality of oyster mushrooms, and even causing them to completely lose their commercial value. This disorder is mainly caused by improper management, and in a few cases by strain degeneration, mutation, or viral infection. The main types of deformed mushrooms are: 1. Tall-stemmed mushroom: the cap is small, differentiation is poor, and the stem is relatively long. The cause is that during the primordium formation and differentiation stage, the mushroom house is short of oxygen, light is insufficient, and the temperature is relatively high, which affects the normal differentiation and development of the cap. Control methods: strengthen ventilation, adjust light and temperature

What to Do About Deformed Oyster Mushrooms? A Detailed Guide to Symptom-Specific Prevention and Control
During oyster mushroom production, inadequate management measures and unsuitable environmental conditions often easily lead to the formation of deformed mushrooms. In production, the causes of deformed mushroom formation should be identified and effective prevention and control measures taken. 1. Spherical or flask-shaped: The stipe of the oyster mushroom is spherical or flask-shaped, the surface is uneven or twisted into a wave-like shape, and the cap cannot form, with only a very small point or obvious icicle-like stripes. This is caused by viral infection, and should be prevented and controlled by spraying or smearing with Virus K, Virus A, or Xiaojunling. 2. Cauliflower-shaped: The fruiting bodies of the oyster mushroom
