Sweet pea cultivation points

First, the soil fertilizer conditions. Legume crops should not be used for continuous cropping, and fertile soil should be selected. Mushi 2000-3000 kg of farmyard manure, 40 kg of phosphate fertilizer, 15 kg of potash fertilizer should be used as base fertilizer, and ploughed into the soil. Second, sowing methods. Sweet peas have a growth period of 90 to 100 days, fresh picking for 30 to 60 days, and adaptation temperature of 15 to 20°C. In different regions, the sowing date should be advanced or delayed depending on the local temperature. 60 cm wide, planted in double rows, with a spacing of 40 cm. It is highly productive and used for chyme. The spacing between plants is 20-30 cm. The main peas are planted with 15-20 cm. Seeds 2-3 seeds per hole, sowing deep 3-4 cm. Third, field management. When the seedlings grow about 5 centimeters, the use of thin human fecal urine plus compound fertilizer 5-7.5 kg raised. Seedling height 30 to 50 cm to take the shelf in order to lead the vine on the shelves. After the shelves can be combined with cultivator weeding, in the flowering and pod period of topdressing compound fertilizer 60 kg per acre. In order to increase the number of knots and improve quality, extra-root topdressing can be performed during this period. The method was to spray foliar with potassium dihydrogen phosphate solution 250 times on sunny afternoon, and spray with 500 times borax solution once a week later. Fourth, control pests. Blight can be treated with 50% carbendazim 1000 times after rooting, and powdery mildew can be sprayed with 3000 times liquid powder to prevent and control. The control of leaf miners can be sprayed with 40% Dimethoate 1000 times every other week after the seedlings are fully grown.
