In the cold winter, the cultivation of kidney beans in greenhouses has become an important part of agricultural management. For farmers, in order to succeed in the cultivation of kidney beans, it is necessary not only to understand the growth Xi of kidney beans, but also to scientifically manage the greenhouse environment. Especially in the early management stage, through reasonable measures, the healthy growth of kidney beans can be ensured, laying a solid foundation for future harvests.
First, choose the right variety
First of all, according to the local climatic conditions and market demand, choose a kidney bean variety that is suitable for winter planting. It is necessary to pay attention to the selection of cold-resistant, disease-resistant, high-quality and high-yield varieties. At the same time, it is also necessary to select adaptable kidney bean varieties according to the environmental characteristics of the greenhouse.
2. Prepare before sowing
Before sowing, prepare nutrient soil and seeds. Nutrient soil should be rich in organic matter, and an appropriate amount of compound fertilizer should be added. At the same time, the seeds should be selected and treated to improve germination rate and disease resistance. About a week before sowing, the seedbed should be prepared in the greenhouse and the ground should be laid to increase the temperature of the seedbed.
3. Fine sowing
When sowing, ensure that the humidity of the seedbed is suitable, sprinkle the kidney bean seeds evenly on the seedbed, and cover it with a thin layer of soil. After sowing, a small arch shed and non-woven insulation materials should be added to the greenhouse in time to maintain the temperature and humidity of the seedbed.
Fourth, strengthen the management of seedlings
In the seedling stage of kidney beans, it is necessary to strengthen management, uncover non-woven fabrics and other insulation materials in time, and let kidney bean seedlings receive natural light. At the same time, it is also necessary to control the temperature and humidity to avoid overheating or cooling affecting the growth of seedlings. When the kidney bean seedlings grow to a certain height, they should be transplanted and planted in the greenhouse in time.
5. Reasonable fertilization and watering
To plant kidney beans in a greenhouse, you should fertilize and water them reasonably. In terms of fertilization, it is necessary to apply sufficient base fertilizer, mainly organic fertilizer, with an appropriate amount of compound fertilizer. In terms of watering, it is necessary to water reasonably according to the growth needs of kidney beans and the condition of soil moisture. The temperature is low in winter, so pay attention to the water temperature should not be too low when watering, so as not to affect the growth of kidney beans. At the same time, it is also necessary to pay attention to drainage and stain prevention, and keep the soil permeable.
6. Prevention and control of pests and diseases
When planting kidney beans in winter greenhouses, it is necessary to pay attention to the prevention and control of pests and diseases. The main pests and diseases are root rot, anthracnose, rust, etc. In order to effectively control these pests and diseases, a combination of agricultural, biological and chemical control methods can be adopted. In terms of agricultural prevention and control, it is necessary to rationally rotate crops and strengthen field managementIn terms of biological control, natural enemy insects or the use of biological pesticides can be introducedIn terms of chemical control, it is necessary to choose high-efficiency and low-toxicity chemical pesticides for prevention and control.
7. Strengthen greenhouse management
In terms of greenhouse management, it is necessary to control the temperature and humidity in the greenhouse. When the temperature is low in winter, it is necessary to pay attention to the insulation materials such as straw curtainsIn sunny weather, pay attention to ventilation to maintain the appropriate temperature and humidity in the greenhouse. At the same time, it is also necessary to remove weeds and dead leaves and other debris in the greenhouse in time to keep the greenhouse clean and hygienic.
In short, in the early management of kidney beans planted in winter greenhouses, it is necessary to select appropriate varieties, prepare for sowing, fine sowing, strengthen seedling management, reasonable fertilization and watering, control pests and diseases, strengthen greenhouse management and other measures to create a bumper harvest foundation, achieve high and stable yield, and improve farmers' economic and social benefits.
