Perennial cultivation techniques of pure sesame oil wheat vegetable

The pure fragrant Youmai produced by Vegetable Research Institute of Chinese Academy of Agricultural Sciences has been planted in Chuanshan Township of Qixing District for more than three years. This variety has strong adaptability, crispy taste, good quality and high market price. It is loved by farmers and consumers. The perennial cultivation techniques of Youmai are summarized as follows.

1. Variety characteristics: plant height 30~40cm, development degree 20~30cm, leaf lanceolate, length 40cm, width 6~10cm, green, smooth leaf surface, cold resistance, heat resistance, tolerance to bolting, strong adaptability, perennial cultivation in open field and protected land, seed amount per mu 30~40g. 2, annual cultivation techniques 2.1 early spring sowing: 1~3 months in the shed sowing seedlings, standard shed 2 ridges, the middle open-ditch, deep turning, watering the sole, seed sowing in the border, covered with seed mud, to cover the seeds for the degree, tiling plastic film (2 layers of film 1 layer of plastic film), generally 10~15 days to emerge, every rainy low temperature time to emerge longer. Remove the plastic film after the seedlings are neat, ventilate, prevent high temperature injury seedlings during the day, and prevent freezing injury at night. 2.2 Summer sowing: 4~6 months open field seedling, select high potential land, 2m continuous ditch, deep ploughing and application of decomposed manure, build ridge leveling. Soak seeds for 3 hours and sow them after they dry. Nurturing seedbed watering sole water, seed spread on the surface of the ridge, and covered with seed mud, watering enough water, in case of high temperature and drought, covering the ridge with sunshade net, uncovering the net in the morning and evening after seedling, seedbed fertilizer water should be moderate, not too dry. 2.3 Autumn sowing: July to September, seed soaking and germination of oil wheat seedlings. The method is to wrap the seeds with gauze and soak them in water for 3~4 hours, then take them out and put them in the refrigerator for 10~15 hours. If 75% of them sprout, they can be sown. It is best to use small arched shed or greenhouse for autumn sowing seedlings. Pay attention to soil moisture after emergence, not too dry and wet, and pull out weeds in time to ensure smooth drainage. 2.4 Autumn and winter sowing: October can be open field seedlings, November, December can be in the greenhouse seedlings, the same method as spring sowing, November to December and early spring sowing the same. 3. Deep ploughing and full base fertilizer application before transplanting and planting. Generally, 3000kg decomposed manure and 80~100kg ammonium bicarbonate shall be applied per mu, 2m continuous ditch and deep groove and high ridge. Seedling age 4~5 leaf planting, strong seedlings, plant spacing 10~15cm, flat bed cultivation. 3.1 Winter sowing: transplanting in greenhouse, covered with plastic film, about 30 days can be listed, yield 1500~18000kg per mu. 3.2 Spring sowing: transplanting in the open field, applying enough decomposed manure and 80kg ammonium carbonate per mu. After planting, irrigate enough root water, in case of drought, promote with fertilizer water, 25~30 days can be listed, yield 1800~2000kg per mu. 3.3 Autumn sowing: July to September is in high temperature and drought season, and often rainstorm, after transplanting should irrigate enough live water, cover with sunshade net for 5~7 days, after living trees in case of rainy days can be removed sunshade net, moderate fertilizer and water, conducive to the normal growth of oil wheat vegetables, 20~30 days can be listed, general yield per mu 1600~1800kg. 3.4 Autumn and winter sowing: Transplant in the open field from October to November, and transplant in the greenhouse in case of cold wave in December. It can be listed in 25~30 days, and the yield per mu is about 1500kg. 4, pest control oil wheat vegetable disease is mainly downy mildew, early spring disease more, need carbendazim and other chemicals to control, pests are mainly aphids, can be used to control aphidin, big meritorious service. 5. Harvesting pure fragrant wheat vegetables is generally harvested 20~30 days after planting, and more than ten leaves can also be harvested at any time according to market needs.
