1. The pea seedling production base chooses
Due to the high quality requirements of the supermarket, the pea seedling production base should choose a place with fresh air, pure water, uncontaminated soil and good ecological conditions. At the same time, the soil layer is required to be deep, the organic matter content is high, and the water storage capacity is strong.
2, pea seedlings planted in the mouth of the arrangement of
Pea seedlings should not be used for continuous cropping. They must be used for 2-3 years of rotation. They can use spring corn and summer soybeans for pure or intercropping. Purely, the general width is 240cm, the width of the sulcus is 20-25cm, the depth is 20cm, and the size is planted. Each line is 4 lines, the line spacing is 70cm, and the small line spacing is 50cm. Intercropping can use spring corn, plastic film watermelon, cotton planting in the winter, and the intercropping with three wheat or broad beans, spring corn, plastic film watermelon, three kinds of reserved space, 2 sets of cotton planting, The line spacing is 30-35cm. Intercropping of pea seedlings can improve the utilization of winter land in intercropping areas, and the effect of increasing farmers' income is very significant.
3, improve the quality of sowing pea seedlings
3.1. Suitable sowing in the local area is suitable for planting in early September. Seeds soaked in water for 1-2h before sowing, and then treated at low temperature (about 5?) for 7-10d, in order to fight for early seedlings and whole seedlings.
3.2. Reasonable close planting of pea seedlings is to harvest young shoots, and planting density should be appropriately increased to increase yield. Although the pea seedlings are different, the hole spacing is generally 15-20 cm, and 4-5 seeds are planted per hole. The net amount is 7-8kg per mu. When planting, if the sensation is insufficient, it is necessary to insist on cultivating sowing.
3.3 The quality and yield of the pea seedlings applied to the base fertilizer are related to the quality and quantity of the base fertilizer, and the base fertilizer must be applied and applied. Generally, the organic fertilizer is 2000-3000kg, and the high-quality superphosphate is 35-40kg. The organic fertilizer is applied before the preparation of the soil, and the phosphate fertilizer is concentrated on the seeding ditch when planting.
4, pea seedlings do a good job in the field management
4.1. Fertilizer management The pea seedlings have higher water requirements. The local autumn and winter seasons are dry and the soil moisture often cannot meet the needs. Therefore, when the soil moisture is insufficient, it is necessary to do a good job of furrow irrigation in time to keep the soil moist and improve the yield and quality. Discharge in time to prevent waterlogging. Under the premise of applying the base fertilizer, there is generally no need for top dressing, but when the pea seedlings have faded leaves, the leaf shape becomes smaller, and the stems are slender, the fertilizer should be applied in time. Generally, 5-6 kg of urea is poured with water.
4.2, pest control autumn and winter cultivation of pea seedlings, the disease is relatively light, generally do not need medication control. Pests are mainly cockroaches, snails, and Spodoptera litura. The control measures must be based on prevention, comprehensive control, and strict control of medication. Use 50% phoxim in 300 ml of acre, mix 30 kg of fine soil, and apply it to the seeding ditch. The snails are trapped with freshly rotted weeds and manually captured for 3-4 mornings. In the early larval stage, Spodoptera litura was treated with 2.5% dish suspension of 1000-1500 times, and it was prevented by 3 times for 6-7 days.
5, pea seedlings harvesting packaging and transportation
When the pea seedlings are 30-40 cm high, the first harvest is carried out, and after harvesting, new branches are produced and then harvested several times. Local open field cultivation, generally received in January. The harvesting standard is 10-13cm long, 2 leaves and 1 heart are suitable, the harvesting is too long, the pea seedlings are old, supermarkets and hotels are not welcome. When harvesting, 2-3 true leaves are kept on the pea seedlings to ensure branching and increase yield. After harvesting, the pea seedlings should be placed in a clean utensil to avoid contamination, and then the packaging should be sorted in time. It is required to remove the pea pea seedlings, remove the tendrils, arrange each pea seedlings smoothly, and then weigh them with a clean kitchen knife at a distance of 10 cm from the heart leaf, and put them into a breathable plastic (food grade) packaging bag, 400 g per bag. . In October-November, in order to prevent fever and deterioration, the packaged pea seedlings should be pre-cooled for about 4 hours at around 5?. Packed in a 10kg foam box before loading. If it can be transported to the destination within 10 hours, it can be transported by insulated car, otherwise it will be transported by refrigerated truck. After November, as long as it can be sold on the same day, it can be pre-cooled.
