How to grow perilla seeds?
1. Suzixi has a warm and humid climate and strong adaptability. It grows vigorously in warm and humid, loose soil, fertile, well-drained and sunny environment, and can be planted in the vast areas from south to north of China. Until the soil is 20 cm deep and raked flat. Fine, make a border, the width of the border and groove is 160 cm, and the depth of the groove is 15-20 cm.
2. The optimum temperature for seed germination is 18-23 degrees Celsius, and the optimum temperature for stem and leaf growth is 20-26 degrees Celsius. Although the newly unearthed seedlings can tolerate the low temperature of 1-2 degrees Celsius, they grow slowly at the seedling stage, and the optimum temperature for flowering is 26-28 degrees Celsius. Generally, the seeds are sown in the middle and late June of 65438+February, and the young leaves are harvested in the middle and early March of the following year and around the end of June. The growth and harvest period of a single crop is more than 6 months. Perilla frutescens has strong regeneration ability, and can be harvested for 8- 10 times in field management, and the yield of fresh leaves per mu is 1000- 1500 kg.
3. Weed regularly before closing the ridge for plant growth, and pay attention to weeding between seedlings in the direct seeding area. When the seedling height in the drill field is 15cm, it should be fixed at 30cm, and the surplus seedlings should be used for transplanting. The plants in the direct seeding area grow fast and the density is high, so the plants grow in vain, and few plants are branched or not. From field planting to ridge sealing, loosen the soil and weed twice.
4. Generally, after each harvest, 20-25 kilograms of high-nitrogen compound fertilizer or other fertilizers with equivalent nutrients are applied, and 600 times of green oolong humic acid foliar fertilizer and 1000 times of biological potassium fertilizer are sprayed to promote the recovery and early growth and rapid development of perilla after harvest. In terms of water management, irrigation and drainage should be done in time at seedling stage to keep the field moist and prevent waterlogging and root rot; When summer is hot and dry, furrow irrigation should be carried out in time to improve the nutrient absorption of crops, improve the color and quality of perilla leaves, and achieve the goal of high quality and high yield.
Growth environment of perilla seeds
Perilla likes warm and humid climate. Seeds can germinate when the ground temperature is higher than 5℃, and the suitable germination temperature is 18 ~ 23℃. The seedling stage can bear the low temperature of 1 ~ 2℃. Plants grow slowly at low temperature and flourish in summer. The suitable temperature for flowering is 22 ~ 28℃ and the relative humidity is 75% ~ 80%. Resistant to humidity, strong waterlogging and drought, especially in the organ formation period of the product, such as too dry air, too thick and hard stems and leaves, too much fiber and poor quality. It has wide adaptability to soil and can grow in the shade.
How to pick perilla seeds?
Perilla frutescens is a very small seed. There are two signs of maturity: the fruit darkens, and then the plant dries up. At this time, pick the fruit and put it on the newspaper or other big things. Rub the fruit and the seeds will fall on the newspaper. Collect it and gently blow off the impurities, and you will see that the remaining sand is the seed. Pack the bottle. You can plant it next year.
How to preserve perilla seeds?
1, soak in boiling water, take out cold water to cool down, take out and let it cool, put it in a fresh-keeping bag and put it in a freezer for freezing.
2, put it in the bucket! Keep it sealed and put some cloves of garlic on it.
