How to improve the planting method of perilla yield

Perilla alias red perilla, red perilla, black perilla, red perilla, wrinkled perilla and so on. Perilla frutescens is the leafy twig of perilla in Labiatae. It is used in medicine with stems, leaves and seeds. Perilla is a comprehensive cross-commodity can be used medicinally, is a common clinical medicine, but also edible. Perilla sprouts have a special fragrance, which is a very popular sprout vegetable in the south and north of China, and it is also a characteristic variety exported to Hong Kong, Taiwan and other regions. Perilla sprouts are rich in vitamin C, potassium, iron, etc., as well as unsaturated fatty acids, which can improve human immunity, alleviate allergic dermatitis, hay fever and other allergic reactions, and have a certain inhibitory effect on influenza virus.

At present, the planting method of perilla is generally planted in the field or greenhouse, that is, through seedling cultivation, planting, and fertilizer and water management according to the conventional methods, these methods do not allocate nutrients reasonably according to the growth characteristics of perilla. As a result, the yield of perilla is low and the quality is poor, and the survival rate of the seedlings is not very high and is easy to be eroded by pests. In the existing technology, the use of compound fertilizer is also advocated to meet the nutrients needed in the growth process of perilla, but there is little disclosure about perilla microbial compound fertilizer.

1. When planting, choose sandy loam which is convenient for drainage and irrigation, loose and fertile, and turn the land deeply. 2500 kg of farm manure was applied to 200kg of microbial fertilizer per mu, in which biological fertilizer was made from the following components. 50-80 parts of rotten leaf soil, 40-90 parts of plant ash, 10-20 parts of urea, 5-10 parts of ammonium sulfate, 2-5 parts of potassium dihydrogen phosphate, 5-10 parts of manure, 0. 05-0. 2 parts of compound microbial agent and 1-10 parts of superphosphate. Then ploughed 15-20 cm deep, raked flat, made into a border 90-100 cm wide; then selected full perilla seeds for disinfection for 10 hours; opened 0. 8-1 cm shallow holes according to the row spacing of 45-55 cm on the finished border surface. 8-1 cm shallow holes, hole sowing according to hole spacing 30 cm × 50 cm hole; seeds mixed with fine copy, evenly sprinkled into the hole, covered with thin soil, watered, and seedlings emerged 6 days after sowing.

2. When the height of the seedling is 12 cm, the seedling should be fixed according to the plant spacing of 25-30 cm and the row spacing of 45-50 cm, leaving 2 plants in each hole. When the seedling height is 30 cm, weed is removed regularly to ensure that there are no weeds in the field, and topdressing is carried out at the same time, applying 1000 kg of human and animal manure per mu, 15-20 kg of urea and 8 kg of calcium superphosphate, watering during drought and paying attention to drainage in rainy season. Finally, in the process of growth, we should pay attention to the prevention and control of diseases and insect pests and take corresponding measures in time.

For the perilla planted in the embodiment, the incidence of diseases and insect pests is less than 5%; the yield per mu is 15-20% higher than that of the prior art planting method.
