Dutch beans, also known as peas, are one of the vegetables that people often eat. The Dutch beans grown in the fall can be marketed after the National Day, and their economic benefits are high. The autumn planting techniques of peas are summarized as follows:
First, the variety selection
At present, the excellent pea varieties cultivated on the production mainly include Taichung No. 11, Taichung Improvement 603, Taichung Improvement 604, and Dadi 610 (preferably coated seeds). The pod size of each variety is different, in principle, it is determined by the merchant's ordering requirements or market consumption habits.
Second, soil selection
Dutch beans are not strict with soil requirements, but they are convenient for irrigation and drainage, with high soil organic matter content, good light, and fertile middle and upper fields. The former is best for early maturing early rice fields, and the harvested flue-cured tobacco fields can also be selected.
Third, a reasonable determination of the sowing date
The altitude of the Dutch bean planting area in the autumn is more than 500 meters, of which the altitude is 500-600 meters. It should be planted from July 25th to August 1st; the altitude is 600-700 meters, and it can be planted from July 15th to July 20th. . Make full use of the advantages of high altitude and cool summer climate, so as to plant as early as possible, and strive to achieve abundance before the National Day and improve planting efficiency.
Fourth, soil preparation and fertilization
After the previous harvest, 50-75 kg of lime (especially the flue-cured tobacco field) and 22.5 kg of borax are applied to the acre, and then the ridge is ploughed by a ridger at 1.1-1.2 m, and the base ditch is applied to the central ditch.
Fifth, sowing
1. Seed treatment before sowing. Each kilogram of seed is mixed with 10% of 35% butyl thiocarbazone dry powder to reduce bird damage.
2. The amount of seeding. The amount of acres used is 3-3.5 kg.
3. Seeding method. Double-row seeding is used, the plant spacing is 20-30 cm, the row spacing is 20-25 cm, the acre is 4500-5000 points, 2-3 capsules are planted per hole, and 2 cm is covered with finely crushed Honda soil. After sowing, spray the kneading dough with Jinduer emulsifiable concentrate 1000 times to inhibit the growth of weeds. If the weather is dry and the surface is white, it needs to be watered to one third of the height and then naturally dried to increase the emergence rate.
6. Field management
1. Water management. Dutch beans require higher soil moisture and air humidity, but they are not resistant to moisture. They should keep the soil moist. In case of drought, they can fill the “horse waterâ€.
2. Rack the vines. The stems of the Dutch beans are soft and easy to fall. When the seedling height is 20-25 cm, the bamboo branches are in the middle of the two rows, and a wooden stick or bamboo tail of about 2 meters long is inserted every 3 meters or so to enhance the supporting force of the bamboo branches, and then the plastic is extended by 30 cm each time. The rope is tied once.
Seven, fertilization
1. Base fertilizer. In combination with the whole hoe, 1500-2500 kg of fully decomposed farmyard manure or 75 kg of commercial organic fertilizer, 25 kg of superphosphate and 10-15 kg of potassium chloride are applied to the ditch in the middle of the shovel.
2. Topdressing. At the seedling stage, the fertilizer was applied once with 1:90 times of urea solution, and the application was carried out once every 10 days. The bud period is 15:15:
15 compound fertilizer 20-30 kg, potassium chloride 10 kg points. After entering the picking period, look at the seedling growth every 10-15 days with urea 5 kg plus
15:15:15 compound fertilizer 10-15 kg.
3. Root dressing. When flowering, use 0.1%-0.2% borax, 0.05% ammonium molybdate, Germany Kang Pu Shima blue foliar fertilizer 500 times liquid root spray 2-3 times, picking period can be used in love more than harvest, plant dragon and other liquid fertilizer Spray 2-3 times combined with spraying pesticide root spray.
Eight, pest control
1. Root rot. In the early stage of the disease, use 50% carbendazim WP 500 times solution, or 50% dikesone soluble powder 500 times solution, or 1% Shensinmycin suspension 1000 times solution for root irrigation, 5-6 days after medication 1 Times, 2-3 times in a row.
2. Powdery mildew and rust. In the early stage of the disease, spray 2 times with 25% nitrile emulsifiable concentrate 3000 times or 25% acetaminophen water 800-1000 times every 7-10 days for 2-3 times.
3. Bean pods. In the flowering period, alternately spray with 24% solution of cyanohydrazide suspension 1000 times, or 5% chlorantraniliprole suspension, or 1500 times of 2.5% enemy killing emulsifiable concentrate, usually in the morning or evening. Good, focus on spray.
Cultivation of peas in autumn should be done in water and fertilizer management and pest control, and strive to achieve high yield during the National Day.
Organic inulin powder is a natural food source of prebiotic soluble fibers. Inulin is a soluble fiber naturally found in many fruits and vegetables like bananas, asparagus, garlic, onions, and more. Our inulin is extracted from the Jerusalem artichoke rhizome. We extracted the inulin by water extraction, ion exchange, membrane filtration, and spray drying, and other processes. Inulin has many health benefits. It can increase calcium absorption and possibly magnesium absorption while promoting the growth of beneficial intestinal bacteria. As a good source of fiber, it contributes to normal bowel function when consumed with a healthy diet comprising a variety of foods.
