Key Points and Detailed Methods of Pea Seedling Cultivation Techniques
The pea is a legume plant we are all familiar with, and it is also a dual-purpose crop for both vegetable and grain use, a vegetable with high economic returns and broad development prospects. So how do you grow peas from seed into seedlings? Let's take a look at the detailed introduction together.
1. Site Selection
Pea seedlings have a relatively deep root system and strong drought tolerance, but they are not tolerant of wet conditions, so when planting, choose a neutral or slightly alkaline soil that has not grown fruit or legume crops for 3-4 years, with a higher terrain, convenient drainage and irrigation, and a loose, fertile texture. When planting, clear the weeds from the ground thoroughly, prepare the soil, rake it fine and level it, and loosen the soil in advance to help the seeds germinate.
2. Sowing Time
Pea seedlings are cold-tolerant but not heat-tolerant, and the most suitable temperature for the seeds is 18-20 degrees, so basically they can be cultivated in all seasons except the high-temperature period in summer. In the south, spring sowing and autumn sowing are generally adopted; spring sowing is generally carried out in February-March, and autumn sowing is generally carried out in September-October, while in warm regions sowing can be carried out in October or January of the following year.
3. Sowing
Before sowing, apply base fertilizer. Generally, apply 1500 kg of decomposed farmyard manure, 30 kg of superphosphate, and 10 kg of potassium chloride per mu. After raking fine and leveling, make beds 1.5 m wide. Sowing uses the method of dibbling. On the bed surface, open holes at a plant-row spacing of 40×15 cm, and sow 5-6 seeds per hole. Generally, 10-12 kg of seed is used per mu. After sowing, cover with soil and water, and keep the soil moist. Under suitable temperature conditions, seedlings will emerge before long, and when the seedlings grow to 8-10 cm with 2-4 true leaves, they can be transplanted.
4. Strengthen Management
After transplanting, apply topdressing twice, mainly with quick-acting nitrogen fertilizer. Each time you apply topdressing, dilute it with water before applying, so as to avoid excessive fertilizer concentration harming the seedlings. Pea seedlings are also susceptible to waterlogging, so after rain, clear the ditches and drain promptly to avoid root rot and seedling death. During long droughts, water to keep the soil moist. During the seedling stage, carry out appropriate intertillage to promote seedling growth. After rain and after fertilizing, properly earth up the soil, and at the same time pay attention to weeding and guiding the vines. Be diligent with the prevention and control of pests and diseases. Common diseases include powdery mildew, yellow spot disease, and yellow top disease, which can be controlled by spraying with thiophanate-methyl, carbendazim, and chlorothalonil.
