I believe that everyone has a certain understanding of the bean, especially many farmers friends will grow their own, the sales in the market is still very good, you can put some in the summer when making chili sauce, very delicious, then today is small I will tell you about its planting time and cultivation techniques.
First, the time of bean planting
1. Concanavalin is a heat-tolerant plant, so it can be planted in spring, summer and autumn. However, there are slight differences in the varieties of bean-planting in each season. We will choose the corresponding according to the seasons. A more resistant variety. Planting in the spring is usually in February and March, summer is planted around May and autumn is planted in August.
2, the temperature suitable for the germination of the bean seeds is preferably between 25 and 30 degrees, and the temperature suitable for the growth of the bean sprouts is preferably between 20 and 25 degrees, and each season The temperature of the sowing month will be somewhat inappropriate, so we should maintain and master the temperature in the field when we plant.
Second, the key points of the cultivation technology of the bean
1. Site preparation
Choose a field with deep soil, drainage and good ventilation, deep ploughing and freezing, and after the spring, squatting and doing sputum, the width is 130 to 150 cm. Combine the preparation of the land with 2500 square meters of fully decomposed farmyard manure.
2, sowing seedlings and colonization
After the final frost, you can broadcast §. The line spacing is 0.8 m × 0.5 m, and 2 to 3 seeds are planted per hole with a depth of 5 cm. After sowing, it can cover the mulch film, increase the ground temperature and promote germination. When the seedlings are released, the membrane is broken in time, and the bean sprouts are taken out to block the membrane eyes. Usually 15 days after sowing, the seedlings emerge. The bean seeds are not easy to germinate, and it is best to carry out seedling transplants.
3. Field management
(1) Fertilizer and water management. Keep the soil moist before emergence, but the water should not be too much to prevent rotten seeds. Control the moisture before flowering, not suitable for multi-watering. The amount of irrigation should be increased after flowering and pod formation, especially when the young pods are 3-4 cm long. After the emergence of seedlings, the top dressing is carried out. When the four true leaves are planted, the first fat is chased. After the pod is placed, the water is used to chase the second fertilizer, and the pods are topdressed for 1-2 times. Nitrogen, phosphorus and potassium should be applied as full fertilizers, and nitrogen fertilizer should be added as appropriate.
(2) cultivating soil. Usually cultivating 2 to 3 times before flowering to increase ground temperature and moisture. Combine cultivating to remove field weeds and properly cultivate the soil.
(3) Plant adjustment. When the main vine is 50 cm long, the vine is put on the shelf. Appropriate removal of lateral vines or toppings and thinning leaves during flowering and pod-forming period is beneficial to increase the pod-forming rate.
(4) Pest control. The main pests of the peas are aphids and pea pods, which can be controlled by physical methods such as yellow plate entrapment and light moth. If necessary, they should be controlled with imidacloprid and taibao. The main diseases are rust, powdery mildew, etc., through crop rotation, rational close planting and other agricultural control measures can be effectively controlled, or sprayed with stone sulfur mixture, triadimefon and other chemicals.
(5) Harvesting and seeding. When the pod is 10 to 20 cm long, the tender pods are harvested at an appropriate time, and harvested in the summer, until the first frost. Generally, 500-750 kg of tender pods can be harvested per acre. Plants with early pods and varieties of traits should be selected as seedlings, and the base pods should be selected as seed. After ripening, pods are dried and stripped for seed storage.
The above is mainly for everyone to talk about the time and cultivation techniques of the bean planting. Have you understood it after reading it? Also want to continue to understand the relevant planting knowledge, you can continue to pay attention to our website!
