Green beans winter cultivation notes
Green beans, also known as beans, beans, and so on, like hi warm, intolerant of frost, nor heat, growth suitable temperature of about 21 °C, flowering and fruiting period requires 18 ~ 25 °C. The climate conditions for the timely growing of green beans during the winter growing season are contrary to the spring cultivation. The early stage is under the condition of higher temperature and drought, and the latter stage is susceptible to low temperature. Therefore, the cultivation and management are different from the spring green beans, and timely planting and guarantee Whole seedlings are the key to achieving high yields. In recent years, the winter climate in Huizhou is warm. In the winter, green beans are cultivated. Before Spring Festival, early spring can be listed, and the economic and social benefits are significant. The temperature in the early stage of reasonable dense planting is higher, the growth is faster, the temperature is lower in the later period, and the collateral development is poor. Therefore, reasonable close planting is the key to high yield. For the Huizhou area, it is generally 1.3 meters wide (with a ditch), two kinds of rows, 10 to 20 centimeters in diameter, with 3 plants per hole. Field management Winter field beans should be planted after field management should highlight the "early" character, early management of water, early fertilization, early control of pests. High temperature during seedling stage, strong evaporation, watering should be timely moisturizing cooling, drainage after the rain, loose soil, to maintain good soil ventilation performance, promote rapid growth of plants, in the short term to form a strong plant type, early flowering and scarring. When vines are pumped, fertilize the seedlings at the side, post-irrigation, support, control of watering during flowering, watering and topdressing after sitting in the lotus root, and applying a small amount of nitrogenous fertilizer after the rain, can alleviate the alfalfa damage and prevent yellowing of the plants. The main diseases of green beans are anthracnose, rust, and root rot. Attention should be paid to timely prevention and treatment. Insect pests mainly include locusts, red spiders, and soybean pods.
