Hybrid Tomato Cultivation Methods and Key Technical Points
How are hybrid tomatoes cultivated? Here is an introduction. For hybrid tomatoes, you can refer to the following cultivation techniques: 1. Raising strong seedlings is the prerequisite for high seed yield. 1. Seedbed preparation. Suitable seedling-raising methods can be adopted according to local characteristics, such as hotbeds, cold frames, greenhouses, plastic tunnels, or electrically heated hotbeds. Because foreign parent seeds are relatively scarce, for safety's sake, greenhouse bed sowing is best. To better control the temperature inside the seedbed, a cold frame is best used as the transplanting bed. The cold frame consists of cold-protection material, polypropylene rope, new plastic film, bamboo strips, and bed soil. The cold frame specifications are 1.8 m wide, and the length can be determined according to the seedling-raising area, but it must be no less than 2 m at the shortest. The female parent transplanting bed must be no less than 2.5 m at the shortest. The bed soil is made by uniformly mixing sieved disease-free field soil, decomposed barnyard manure, and decomposed horse manure in a 5:3:2 ratio, with a thickness of 20 cm, and the bed surface is 10 cm deep from the ground.

Key Technical Points for Off-Season Cultivation of Straw Mushrooms in Winter
The entire straw mushroom production process takes place in a high-temperature, high-humidity environment, so there are many insect pests and contaminating microorganisms. The main contaminants are ink cap mushrooms (Coprinus), Trichoderma, and Penicillium. The main causes of ink cap mushrooms are a relatively high nitrogen content in the raw materials, a relatively low pH value, and incomplete fermentation and disinfection. Trichoderma and Penicillium are mainly due to insufficient fermentation, relatively...

Key Technical Points for Spring Pest Control and Fertilization of Mulberry Trees
First, pest control must be strengthened. The pests harming mulberry trees in spring are the "mulberry looper" and the "mulberry tussock moth," which mainly feed on mulberry buds and tender leaves. For control, during the mulberry bud stage, a 1000-fold dilution of "dichlorvos" solution can be sprayed; once the mulberry leaves have grown larger, manual catching is the main method. Second, fertilize at the right time. Applying spring fertilizer promptly can promote...
