Sesame high yield cultivation
In the past two years, the Agricultural Bureau of Xiangyang District, Xiangfan City, Hubei Province has adopted a combination of research and demonstration methods on the basis of summing up the experience of mass production increase, and has vigorously promoted the implementation of supporting technologies to achieve a sesame yield of over 150 in a large area. kg. The main cultivation techniques adopted are:
High-yield disease resistance
Through the demonstration results in recent years, the Eichi No. 2 variety has the characteristics of wide adaptability, high yield, and strong resistance, and it has been widely applied.
Fertilizer
According to the conditions of soil fertility and the principle of production and fertilizer, the fertilization standards for 150 kg per mu are: nitrogen 13.5 kg, phosphorus 4.5 kg, and potassium 6 kg. The method of fertilization was sowed from past ploughing and fertilization, and then changed to fertilization and ploughing. The average application rate was 65.1 kg of ammonium bicarbonate, 53.55 kg of superphosphate, 0.5 kg of potassium dihydrogen phosphate and 0.5 kg of bio-potassium. In the flowering period (late July), 0.15 kg of potassium dihydrogen phosphate and 50 kg of water were used to spray the fertilizer.
Grabbing robbers to ensure full seedlings
According to the Daejeon investigation, the 73.5 kilograms of per annum sown on May 26, 65.5 kilograms per acre sown on June 4th, 20 kilograms and 12 kilograms higher than the 53.5 kilograms per acre sown on June 16. The results of the survey showed that 1 kg of sesame seeds and 1.09 kg of sesame seeds were harvested every morning. As a result, high-yield fields can be harvested, plowed, and planted in accordance with the draught, season, and lyrical conditions. They are all broadcasted in early June. Sowing method, using sowing, sowing 0.5 kg, due to timely sowing after the broadcast, security, neat emergence.
Ditch for protection against seedlings
The impact of environmental conditions on the growth and development of sesame is more than that of waterlogging and drought. The prevention of waterlogging, drought, and seedling protection are the preconditions for seizing high yield, stable yield and improving quality of sesame. Therefore, the sesame seeds should be split in time after sowing. The width of the sesame is 2.3 to 3 meters, the depth of the ditch is 0.2 meters, and the depth of the ditch is 0.26 to 0.33 meters. During the mid-fertility period, the gaps in the car ditch are cleaned for the weak link, so that the clear water can be discharged, the dark water can be filtered, and the drought can be filled.
As early as possible to ensure strong seedlings
In order to prevent grass shortage and seedling shortage, generally three grasses are required to complete the full moon. Combine Dingxiong Dendrobium with 1 seedling to open seedlings, 2 pairs of true leaves to open seedlings, 3 to 4 pairs of true leaves to set good seedlings, and 1 seedlings per mu. More than 12,000 strains must be guaranteed. In the case of continuous rain, unable to seedling grass, first, to take artificial seedlings, assault Dingmiao; second is to carry out chemical weeding, in the weeds as soon as the leaves to the two-leaf, the mu fine steady kill 50 ~ 60 Soaring 50 kilograms of water to spray, the weeding effect can reach more than 85%.
Control disease and stabilize high yield
The sesame disease in Gangbei of Hubei Province is one of the three major obstacles to its high yield. In order to ensure that sesame is well developed throughout the growing season, foliar spray should be applied to the water with 4 kg carbendazim suspension 0.1 kg and 50 kg water for sesame buds (mid-July) and flowering (early August). The control effect can reach more than 90%.
The bearing structure, fixed film systems and installation of this greenhouse is relatively simple. And due to it, raw material and manufacturing costs are affordable. Except the high strength woven film is higher, other kinds of antidrop film are economical. In general, the comprehensive cost of film greenhouse is lower 30% ~ 50% than the same size and specifications of the other types of greenhouse.
