(1) Turning often, removing damaged and insect-infested seeds; removing most of the pods by singing the dried sesame seeds twice in advance; weighing the selected seeds into clean water and allowing them to stand for 1 hour each time. After stirring for half an hour, the floating seed is finally removed, and the saturated seeds that have settled on the bottom of the water are placed in a plastic container, soaked in warm water at 30° C. for 12-18 hours, and the water temperature is adjusted and agitated every 3 hours to increase the germination rate. The budding uniformity.
(2) Disinfection treatment of seeds: Remove the seeds soaked in (1) and put them in a sieve basket to control the water for 30 minutes, and then use 50% carbendazim wettable powder for dressing (the amount of powder is 5 %0, seed dressing for uniformity), dry.
(3) Preparation of nutrient mash: AM fertilizer, zinc sulfate, manganese sulfate and ternary compound fertilizer (N:P:K=16:J6:16) organic fertilizers are mixed uniformly according to 1:2:2:30:1000. Formulated fertilizer, and then mix formula fertilizer and soil by 1:50 mix Serve nutrients matrix; the use of nutrient enamel matrix with a diameter of 8cm, depth of 12cm rake system.
(4) Germinating and picking up: (2) The treated seed is put into a cloth bag and kept in the haystack. The germination is maintained under the condition of 25°C, and it is turned every 6-8 hours to find that the seed coat of the seed begins to be frayed. When the dew is white, it can start to sow; when sowing, each pod will be placed in a nutrient bowl containing formula fertilizer in a greenhouse or a large plastic shed; when the seedlings in the pods grow two true leaves It can be transplanted into Daejeon. Formula Fertilizers are rich in phosphorus, calcium, and potassium to provide superior micro-habitat for the growth of sesame seedlings, promote their robust growth, increase disease resistance, and reduce the occurrence of diseases and insect pests such as bacterial wilt. Appropriate early cultivation time.
(5) Keep the soil weakly alkaline: Keep the soil weakly alkaline in sesame planting areas. When the Ph value of the soil is lower than 7, apply alkaline substances such as lime to make the soil PH value greater than 7 weak alkalinity to prevent the soil from appearing. Acidity can easily cause diseases such as sesame wilt.
(6) Daejeon treatment: In early April, apply 2,000 kg of organic fertilizer and 10 kg of urea 10 kg of urea 10 kg per acre immediately to deep tillage and leveling, and then build a ridge with 30cm width and 10cm height, and dig 30cm deep between ridges 30- 35cm drainage ditch;
(7) Compound planting: When sesame is planted, a 20cm deep hole is to be punched every 80cm in the center of the ridge to remove a layer of AM bacterial fertilizer matrix, and the sesame seedlings are planted in the hole to be irrigated, but it is necessary to pay attention to the base of the seedling. Slightly higher than four weeks; in the ridge between the sesame seed planting oil vegetable oil 1-2 points Shadou, on both sides of the rows of sesame sowing between the two rows of early spring soybean sowing, when the pods can be picked when the timely picking and pods buried Into the bottom of the gutter for green manure, then loose soil sowing summer beans, summer soybean meal can be picked when the sale, stems for green manure, spring and summer soybeans are sown with ammonium molybdate solution seed dressing, the amount of ammonium molybdate soybean seed Dry weight of 2%; lentils after harvest, also for green manure; autumn harvest fertilization, soil preparation planting winter vegetables radish, broad beans, cabbage, etc., broad bean pods for green manure, small dill l, planting oil plants after harvest; In the spring, the sesame seeds are planted in the position of this year's drainage ditch, alternating in turns; high-ridge cultivating sesame, oil stalk, sorghum and other good-tolerant and early-tolerant plants, planting hi-fat soybeans beside the rows of drains, making full use of time and Space can produce huge Economic and ecological benefits: Sales of oil bean, wolfberry fruit, vegetable pods, radish, broad beans, cabbage, etc. can greatly increase the annual yield of mu; AM symbiosis with plant roots not only increases the plant's ability to absorb nutrients; various types of green manure In the underground fermentation decomposition and formation of humus and a variety of nutrients supply balanced nutrition, improve plant disease resistance, enrich soil microbial communities, reduce pathogenic bacteria.
(8) Promoting fruit setting: In addition to chasing nitrogen, phosphorus, and potassium fertilizers in the soil when the first primary ear of the sesame seed begins to bud, it is necessary to spray 0.1-0.2% boric acid, manganese sulfate, and sulfuric acid at the flowering stage. The zinc solution was sprayed once every 5-8 days and sprayed 2-3 times in total to improve the plant's resistance to disease and promote pollen development and pollination.
