Several Measures and High-yielding Cultivation Techniques for Realizing Early Sowing of Summer Sesame
Most of the main sesame producing areas in China are planted in summer sowing. For a long time, the output is low and unstable, which is related to frequent disasters, but the more important reason is that the sowing date is too late, the growth period of sesame is short, and the climate resources are not sufficiently reasonable. Use, in order to solve this problem, in recent years, we have carefully studied how to sow sesame in advance sowing and supporting cultivation techniques, preliminarily summed up a set of high-yield cultivation techniques. 1 Analyze the Causes of Early Seed Production Increase in Sesame 1.1 Make full use of climate resources China's major sesame production areas, including Huaibei, Jianghan Plain, and Nanyang Basin in Henan, Hubei, and Anhui provinces, are located in the middle latitudes of the East Asian continent and have typical monsoon climate characteristics. From late May to early September, it is the most abundant and abundant period of light and heat resources in a year, and it is also suitable for the growth and development of sesame. The sowing date of summer sesame is early to mid-May, and the latest at about the 1st of June makes the maximum utilization of the climate resources at this stage. This is more than the effective accumulated temperature and sunshine hours during the whole growth period of the sesame seeds sown after wheat harvesting. Sesame seeds are a kind of good-heat and good-light crops. When the weather conditions are suitable, they have the habit of continuous growth and continuous flowering. Due to the increase in effective accumulated temperature and sunshine hours, this laid the foundation for achieving high yield in summer sesame seeds. 1.2 Avoid or reduce the impact of severe weather. Sesame generally emerges in late May and can sprout before the end of June. The temperature during the entire seedling period is not too high, the sun is light, and the atmosphere is dry, which is conducive to the early and steady growth of sesame, 7 After the month, it gradually enters the flood season. At this time, as long as the flood prevention work is done, the high temperature and abundant precipitation are conducive to the vigorous growth and blooming of the sesame seeds. After the mid-August period, after the flood season has passed, the temperature is significantly reduced, but at this time, the sesame seeds are close to the top of the ceiling, and the relatively dry weather is conducive to strong sesame grouting. Therefore, the early sown sesame seeds exhibited high plant height, low leg height, multiple pods, and large pods. The grain was full, the grain weight was high, and the yellow tip was short and sharp. 2 Several measures to achieve early summer sesame sowing 2.1 Wheat glutinous interplanting sesame 2.1.1 The best time for wheat glutinous interplanting sesame Before and after May 20, it is the best time for wheat glutinous interplanting sesame seeds. During this period, compared with wheat harvest, rainfall is guaranteed, soil moisture is good, and the amount of evaporated air is low, which is favorable for sesame seedlings. Compared with wheat ploughing, wheat hull interplanting sesame seeds has an effective flowering period of at least 10 to 15 days, which lays the foundation for the high yield of summer sesame seeds. 2.1.2 Selection and planting methods of former glutinous wheat varieties Wheat varieties (such as Yumai 18 and Zhengmai 9023) with dwarf, early maturity and high yield were selected and planted in width 24cm and narrow row 12cm. In the management of wheat, control water and fertilizers and implement chemical control techniques to prevent the lodging of wheat. Chemical weeding is used to eliminate weeds in wheat fields so that wheat can be interplanted in field operations. In the wheat fields sprayed with chlorpromazine after December, sesame seeds should not be grown in the coming year. 2.2 Interplanting sesame seeds between rows of garlic 2.2.1 Optimum period of interplanting sesame with garlic The best period for interplanting sesame with garlic sprouts is around May 15th. During this period, 90% of the leaves of garlic are in the senescence period, which is the field operation The favorable period of sesame. 2.2.2 Planting garlic with interplanting sesame Generally, garlic spacing is 21~24cm, and sesame seeds are sown in a 2:1 manner. In the case of insufficient soil moisture before sesame sowing, first garlic can be used to send old water, which is beneficial to sesame sowing. 2.3 Iron pods sowing sesame 2.3.1 When the wheat is sowed at the time of harvest, it shall be sown according to the nymph. The sesame seeds sown in this period and the sesame seeds sown in the plowing field can enter the flowering period 5 to 7 days ahead of time. Otherwise, the sesame seeded sesame seeds will enter the high temperature and rainy season shortly after emergence, causing the plants to grow in length and affecting the ripeness of the sesame filling. Therefore, cultivating sesame seeds after wheat ploughing tends to result in plant dwarfs, high legs, thin pods, small pods, grainy pods, and slightly yellowish pods. 2.3.2 Method of wheat mash sesame sowing Wheat should be robbed after sowing, the method is: 1 picking the situation is sufficient, the first use of hydrazine diammonium phosphate (or monoammonium phosphate) 10 ~ 15kg, then the seed antecast . 2 good sowing technology can diammonium and sesame seeds mixed together sowing. Keep in mind that the mixed sowing of fertilizer should not be excessive, otherwise it will affect the emergence of sesame seeds. 3 When the sensation is insufficient, but does not affect the emergence of seedlings, sowing sesame seeds, and other sesame seedlings to the budding stage with the same quantitative fertilizer. The three above-mentioned sowing methods should be adopted to promptly polish and protect the crops after sowing, so as to facilitate emergence. 3 High-yielding cultivation techniques for sesame seedlings 3.1 The results of reasonable dense planting density test indicated that the planting density of high-yielding fields should be controlled at 8000-9000 plants per acre, and general planting capacity should be 10,000-12,000 plants per mu. 3.2 scientific fertilization Sesame fertilization should be scientific, the principle of fertilization is to control nitrogen fertilizer, increase potassium fertilizer, general medium conditions, Mushi pure nitrogen 5 ~ 6kg, phosphorus pentoxide 5 ~ 6kg, potassium oxide 3 ~ 5kg, sowing When applying 10 ~ 15kg of diammonium phosphate as a seed fertilizer, buds and then apply 5 ~ 7.5kg of urea as flower bud fertilizer, potassium-deficient soil should be properly added potassium fertilizer, when the sesame cap period found that plants have defertilizer phenomenon, combined with Rain or irrigation sprinkle 1.5 kg of urea per acre, to promote sesame seed grouting, to reach the upper seed full grain weight. 3.3 Field Management 3.3.1 Seedling Management After the emergence of sesame seeds, the former crops have been harvested and weeding shall be conducted in time to prevent seedlings and grassland. 4 After fixing the leaves of the true leaves, topdressing and rooting were carried out under conditions of sufficient sensation. 3.3.2 Drought-proof row of sesame field blocks, according to the terrain, digging good sulcus, gutters, to reach the same three-channel, so that the water can discharge, dark water can be vented. After entering the flowering period, it has a great influence on the growth of sesame. For instance, in the afternoon, when the leaves of the plants are found to be wilted, they should be watered in time to prevent the growth from being stopped due to drought, falling flowers, falling buds, and flowering and capping in advance. 3.3.3 Prevention and control of pests and sesames During the growth of sesame, it is necessary to focus on comprehensive prevention and control of pests and diseases, especially in the chemical prevention and control to take a variety of comprehensive prevention and control, close to prevent underground pests in the seedling stage, spraying once every 7 days after the fixed seedlings, drugs used in general The carbendazim, thiophanate-methyl, virus A, losben, and enemy killings are effective for control. Rotating spraying, spraying potassium dihydrogen phosphate, borax and anti-aging hormones etc. during spraying at full flowering stage, thus reducing the loss of pests and diseases, and reaching the late-stage requirement for fertilizer and delaying aging. 3.3.4 The results of topping and leaf protection and timely harvesting tests showed that the sesame topping had a yield increase of about 10% compared with no topping, and the time for topping was before and at the end of July in the spring sowing pod, and the sesame seeds were sown on August 5 to 7 ( 7 days before the beginning of autumn) The length of the topping is within 1 cm. Sesame leaves in the last flowering period of the sesame seedlings are very important, and the leaf production is reduced by 23.3% compared to the non-leaving leaves. The earlier the leaves are removed, the greater the reduction in output. When the sesame seedlings show pods or the seeds in the middle of the plants appear as the inherent color of the seeds, the sesame seeds can be harvested.
