Covering cultivation with mulching film can make sesame per mu more than 150 kg, and some can exceed 200 kg. Therefore, mulching is an effective cultivation measure to achieve super high yield of sesame. The specific technology is introduced as follows:
1. Choosing a timely and early seeding: After the mulching film is covered, the effective growth period of sesame is prolonged. Therefore, it is necessary to use medium-late ripe sesame varieties with high susceptibility to sputum, disease resistance and high yield, such as Yuzhi No. 5, No. 7, No. 8 and sesame hybrids. It is suitable for early sowing, and the sowing date is from the end of April to the beginning of May. Use the growing season to increase sesame production.
2, soil preparation fertilization ridge: increase the application of phosphorus and potassium fertilizer, control the amount of nitrogen fertilizer. When the yield of sesame seeds is more than 200 kilograms, about 20 kilograms of nitrogen, phosphorus and potassium are applied. In the fertilization method, the base fertilizer is the main factor, and the flower topdressing and leaf top dressing are supplemented. Half of the total phosphorus and potassium fertilizer and total nitrogen were used as the base fertilizer, and the remaining half of the nitrogen fertilizer was used as the top dressing. The mulch must be ridged, usually one ridge every 80 cm, the ridge surface is 45 cm wide, the groove width is 35 cm, and the ridge height is about 10 cm. 2 rows per ridge, with an average row spacing of 40 cm.
3, sowing and film: the film sesame can be used for stripping, generally can be sown after the cover film, the width of the film is 70 cm, in order to reduce the production cost, generally use linear low-density polyethylene micro-film (local film thickness is At 0.008 mm, about 6.5 kg of mulch is required per mu. The film can be mechanically or manually, but the ridge surface should be flat, the film and the soil surface should be firm, and the film should be tightly sealed. In addition, the pre-emergence soil is treated with a herbicide before the film is mulched to prevent weeds.
4, chemical regulation: before sowing with 100 mg / kg -150 mg / dry grams (ppm) with dip soaking seeds or spray 150 mg / kg (ppm) in the seedling stage, promote root shoots.
