What should be noticed in sweet pea cultivation technology?

Sweet is a variant of pea, a semi-cold plant. The pods are round, sweet and nutritious, and taste good. It is a new high-end vegetable pea variety. At present, the market needs to be large, and the market prospect is promising. The cultivation points are introduced as follows.

(1) Soil and fertilizer conditions

Leguminous crops are not suitable for continuous cropping. It is advisable to choose fertile and loose soil, and apply 2000-3000 kg of peasant fertilizer per mu, 40 kg of phosphate fertilizer, 15 kg of potassium fertilizer as base fertilizer, plow the soil into the soil, and fine-grained tiller.

(2) Seeding method

The growth period of sweet peas is 90-100 days, fresh pods are collected for 30-60 days, and the adaptive temperature is 15-20 ° C. Different areas, according to local temperature, advance or delay the planting period. The pupae are 60 cm wide and double-row planted with a row spacing of 40 cm. Because of their high tillering properties, they are used for pod-eating plants with a plant spacing of 20-30 cm. They are mainly pea-eating with a plant spacing of 15-20 cm. Seed 2-3 seeds per hole, sowing depth 3-4 cm.

(3) Field management

When the seedlings are about 5-7 cm long, thin human feces and urine can be added per acre, and 5-7.5 kg of seedlings can be lifted. 35-50 cm high seedlings must be set up so that the vines can be put on the shelf. After being put on the shelf, it can be combined with weeding and weeding, and 60 kg of compound fertilizer can be applied per acre during the flowering and pod-setting stage. In order to increase the number of pods and improve quality, during this period, topdressing micro-fertilizer can be combined. Method: Spray the foliage with 250 times potassium dihydrogen phosphate solution on a sunny afternoon, and then use 500 times borax one week later The solution was sprayed once.

(4) Control of pests

Root blight can be controlled by irrigating the roots with 50% carbendazim 1000 times solution after emergence; powdery mildew can be controlled by spraying with powder rust 3000 times solution. To prevent and control leaf miners, spray with 1000% solution of 40% dimethoate EC every 1 week after the whole seedlings.
