The illumination time is longer from August to September every year, which is suitable for plant growth and development. Moreover, the high temperature and humidity are beneficial to the germination and growth of plants. Before planting pea tips, it is necessary to soak their seeds in warm water to make them absorb enough water, thus improving the germination rate of plants, and then sow pea seeds evenly in loose and fertile soil.
Pea tip is the uppermost part of pea seedling. It is the new tender tip of pea and a unique ingredient in Sichuan. Pea tip is no ordinary pea seedling. In the farmer's words, if you pick the pea tip, you won't bear peas again. Pea tip in autumn is also sold in the street, but the fiber is still a little thick and tastes bad.
Field management of pea tip
1. Reasonable close planting: Pea seeds for producing pea tips are suitable for direct seeding and should be properly close planted. The row spacing is 30-40 cm, the nest spacing is 20-25 cm, and 3-5 seeds are planted in each nest. After sowing, cover with 2-3 cm thick loose soil.
2. Chemical weeding: After sowing and before emergence, chemical herbicides can be applied to the land with more weeds, and the soil should be closed to kill weeds. Attention should also be paid to weeding during pea growth, mainly by manual weeding.
3. Never water peas before they emerge to prevent seeds from rotting; Generally, 2 ~ 3kg urea is mixed with light animal manure for 10~ 12 times after full seeding; After the first harvest, 65,438+00 ~ 65,438+05 kilograms of urea per mu were mixed with clear water to raise seedlings. After each harvest, use 3~5 kilograms of urea per mu. In case of drought, sufficient water should be poured to keep the soil moist, so as to promote the hypertrophy of pea tips and increase the yield of pea tips. It is best not to add human feces when watering, and keep it clean and hygienic.
