“Mr. Cai, you have come just right. Could you please explain us the cultivation techniques of autumn cowpeas?†On August 8th, Cai Jianguo, a senior agronomist and vegetable grower from Nanjiang County Bureau of Agriculture, came to work in Shahe Town. In the village, the villager Liang Guogui said. Lao Cai said that in the fall, kidney beans grow fast and supply the market before and after National Day.
, high prices and good returns. The growth and development of autumn cowpea are at the transition stage from moderate to low temperature, with higher temperature in the early stage and more rainwater, which may cause pests and diseases easily. Therefore, in order to grow autumn cowpeas, we must put a good six pass -
Choose a block
The fields in which cowpeas are planted in the fall should be planted in plots that are not heavy, fertile, loose, and have convenient drainage and irrigation. Before ploughing the land, the residue of the former hoe should be thoroughly removed, and the burrowing or deep burial outside the field should be concentrated to reduce the number of culprit sources. The depth of the ploughing area should reach 30 cm or more and it should be 3-4 days.
Afterwards, cultivating and leveling, reaching the level of earth broken, specifications for the car, and apply pollution-free and cooked farmyard fertilizer 4000 kg, 30-40 kg of superphosphate, 150 kg of plant ash or 30-40 kg of potassium chloride, biological bacterial fertilizer Enzyme bacteria 4000 kilograms or steadily high "301" 60 kilograms as the base fertilizer, covered with flat ditch to be broadcast.
Prepare varieties
The main requirements for cultivation of cowpeas in the fall are: strong disease resistance. Followed by a wide range of adaptability, insensitive to light requirements, and then relatively concentrated.
Timely sowing
Autumn cowpea sowing should not be late. At the latest no later than August, the planting is relatively early, and the period for harvesting will be long. The yield is high and the benefit is good.
Before sowing, it is necessary to select seeds, remove pods, half seeds, miscellaneous seeds, mildew seeds and other sundries. In the live broadcast, the spacing of the sown plants was 60 cm and 30 cm, and the plants were planted in double rows, losing 2-3 seeds per pot.
Watering to work
The temperature is high in the early autumn and evaporation is high. Therefore, we must pay special attention to do a good job of irrigation and promote the growth of cowpea. The seedling stage is at a high temperature, and the watering must be diligent. Every 3-5 days, it is poured once to cool the soil to keep the soil moist, especially for watering sooner or later. If it is a hot weather, sudden rainfall should be timely irrigated with well water to avoid injury. .
Flowering and scarring: appropriate control of watering, usually 5-7 days watering once. After sitting, the pods begin to elongate, and then the amount of watering can be increased, once every 3-5 days, to keep the soil moist. In case of continuous rainy weather, it is necessary to clear the trenches in time, drain the water, and stop the rain.
Fertilizer as appropriate
On the basis of applying base fertilizer to the formula, it is “early top-dressing, ground top-dressing, frequent meals, and light before and afterâ€. Fertilizer planting seedlings by 30-40 kg per mu or 10 kg of urea, bio-fertilizer bacteria pellets 100 kg of watered or dredged water irrigation. When the pods are spread, the racks are inserted firmly, and the riot-proof wind blows the brackets.
Ring beans grow.
During the flowering stage, the top dressing is applied twice. Each time, the application of urea is 15 to 20 kilograms per mu or the Huifeng 125 ml watered 60 kg foliar spray. After harvesting, according to the conditions of the seedlings, it is appropriate to combine topdressing with watering.
Weeding and weeding
In the early autumn, the temperature is high and the rainfall is abundant. It is conducive to the spread of diseases, weeds and weeds. In particular, weeds grow rapidly. If weeds are not removed in time, weeds can easily cause grass shortage, causing weeds and cowpeas to compete for water and affect the growth of cowpeas. . At the same time, due to overgrown weeds, it will provide pests with places and sources of disease transmission, posing a serious threat.
Kidney bean production, so the middle weeding must be carried out.
General requirements in the seedling stage weeding 2-3 times, after the scaffolding pull the grass 1-2 times, to clean the pastoral, reduce the risk of pest damage. The first cultivator should be shallow, light, and uniform; the second cultivator should be a little deeper, and the culvert should be deep and deep; the third cultivator should be straight and ridged to form a half-height ridge, which is conducive to a good field management.
