Transplanting crops in Daejeon: It is not easy to pick a place for selection, and it is not allowed to re-taste a thin sandy land or a hillock than a ridge. Fourth, field management. Weeding and weeding, two shovels and three crops, from the beginning of the rainy season in early July, during the bud stage, optional sunny days with 0.2% potassium dihydrogen phosphate foliar spray, to promote flowering and improve the yield and quality, increase the pigment content, increase the level . Fifth, take summary points. 70% to 80% of the flowers have been fully opened, and the micronuclei can see the stamens (ie, the flowers and seed coats do not turn black) can be harvested. According to the two-year planting experience of the farmers in our town, the marigold seedlings are generally 3500-4000 strains, and each plant can produce 0.8-1.2 kg of flowers. This year due to drought and less rain, defertilization, resulting in weak flowers, short flowering, premature aging. However, the average household's mu yield is about 3,000 pounds. If the yield per mu is 3,000 pounds, the purchase price is 0.28 yuan/kg, and the per mu output value is 840 yuan. Remove the cost, mu income of 670 yuan, 500 yuan per mu net income. If everything is normal, 4000 seedlings per mu will be planted, and the yield per plant will be 1.2 pounds, which is an increment of 4800 pounds, the purchase price will be 0.28 yuan, and the mu income will be 1,344 yuan.
