How to control field bindweed in sesame fields? Oxadiazon can control it
Liu Bengui from Shou County, Anhui Province, called to say that in recent years field bindweed has been severe in local sesame fields, and common herbicides cannot control it; he does not know which herbicide should be used to control this weed. According to relevant information, for chemical weed control in sesame fields, before sowing sesame, use 80-100 ml of 48% trifluralin emulsifiable concentrate per mu, or 50-70 g of 70% prometryn wettable powder, add water and spray evenly on the soil surface, then immediately incorporate into the soil to a depth of 3-5 cm; this can control annual grass weeds and some broadleaf

How to Ensure Full Seedling Emergence in Summer-Sown Sesame? Key Technical Points Explained
Ensuring full seedling emergence from a single sowing of summer sesame is an important measure for increasing summer sesame yields per unit area. However, during the summer sesame sowing period, temperatures are high and the weather is changeable. If drought occurs, seedlings are easily "baked to death," causing severe gaps in the stand; if heavy rain occurs, seedlings are easily "smothered to death," also causing gaps in the stand. It is recommended to use the double-layer sowing method to achieve full seedling emergence from a single sowing of summer sesame. For mechanized sowing, sow 0.7 kg per mu using a 24-row seeder, of which 12 rows sow at a deep layer with a depth of 3-4 cm, and the other 12 rows sow at a shallow layer with a depth of 0.2 cm, with two passes of compaction before and after sowing. For manual sowing, first

Timely Early Sowing Measures and High-Yield Cultivation Techniques for Summer Sesame
The main sesame-producing areas in China mostly practice summer sowing, and for a long time yields have been low and unstable. This is certainly related to frequent disasters, but the more important reason is late sowing, a short growth period for sesame, and inadequate and irrational use of climatic resources. To solve this problem, in recent years we have carried out careful research on how to sow summer sesame earlier and on supporting cultivation techniques, and have preliminarily summarized a set of high-yield cultivation techniques. 1 Analysis of the reasons for increased yield from early sowing of sesame 1.1 Full use of climatic resources The main sesame-producing areas in China, including Henan

Taiwan engineers cultivate sesame nutrient rice via genetic engineering
Researchers at the Graduate Institute of Biotechnology of National Chung Hsing University in Taiwan, China, used genetic engineering technology to improve the nutritional value of rice, successfully breeding sesame nutrient rice. The researchers inserted the gene for sesame 2S albumin into the Tainung 67 rice line, cultivating a new rice variety containing sesame 2S albumin, which they named sesame nutrient rice. Sesame nutrient rice mainly increases the methionine content in rice protein, making the amino acid composition of rice protein better match human needs and enhancing its nutritional value. Generally speaking, plant proteins are lower

Introduction to the Space Sesame Jinzhi No. 8 Variety
Jinzhi No. 8 is a new super-high-yield sesame variety recently developed by Chinese research experts using high-tech space breeding technology. It is disease-resistant and waterlogging-tolerant, with a high oil yield, and has great promotional value. Its main characteristics are introduced as follows: Super-high yield: Jinzhi No. 8 is an indeterminate-growing sesame variety per plant, with an average plant height of about 2 m, reaching 2.5 m in plots with good fertilizer and water conditions. Due to a series of high-tech breeding methods such as space radiation, the plants are exceptionally sturdy, with large leaves and a low capsule-bearing position. The average number of capsules per plant is about 150, with a maximum of 27

Detailed Explanation of Key Points for High-Yield Cultivation Techniques of Summer Sesame
Sesame belongs to the Pedaliaceae family, genus Sesamum, an annual herbaceous plant that prefers warmth, and its varieties include both black and white types. Besides being used for food, sesame oil is also a high-quality raw material for several daily-use industrial products and a lubricant and protective agent for the machinery industry, and its by-products are all good feed and fertilizer. In short, growing sesame well is of great significance for improving people's lives, developing industry and agriculture, supporting the country's socialist construction, and increasing the collective economy. In China, sesame cultivation is divided by sowing season into spring sowing, summer sowing, and autumn sowing.

Key Fertilization Techniques for Summer Sesame in the Mid-to-Late Growth Stage
For high-yield cultivation of summer sesame, fertilization should include heavy and shallow application of base fertilizer, a moderate amount of seed fertilizer, heavy application of flower bud fertilizer, and supplemental spraying of phosphorus and potassium fertilizers; organic fertilizer should be the main type, combined with phosphorus and potassium fertilizers, while chemical fertilizer use should be minimized as much as possible to improve sesame quality. To produce every 100 kg of sesame, the fertilizer requirement is: nitrogen fertilizer 6.24-8.13 kg, phosphorus fertilizer 2.19-3.28 kg, potassium fertilizer 6.24-10.19 kg. However, in summer sesame cultivation in our province, most farmers do not apply base fertilizer, and for topdressing they only apply urea or a small amount

Key Points and Methods of Fertilization Techniques for Summer Sesame
To achieve higher yields of summer sesame, nitrogen, phosphorus, and potassium fertilizers need to be applied skillfully at the right time. When fertilizing, attention should be paid to mastering the principles of one steady, two precise, and three heavy. One steady means fertilization at the seedling stage should be steady. Summer sesame grows slowly at the seedling stage, and the root's ability to absorb nutrients is weak. If the base fertilizer is insufficient, it will cause the seedlings to be thin and weak. The seedling-promoting fertilizer should be topdressed as early as possible, but the amount of fertilizer used should be small, otherwise it is very easy to cause leggy seedlings. Two precise means topdressing at the bud stage should be precise. From the bud stage to the early flowering stage of summer sesame, the growth rate noticeably accelerates. If topdressing is timely at this time, it can promote flower bud differentiation and increase

Chemical weed control in summer sesame fields should be carried out at the right time
The seedling stage of summer sesame coincides with the hot, rainy season. The roots are few and the growth is weak, while weeds emerge quickly, are dense, and grow vigorously, easily shading the sesame seedlings and causing a weed infestation. Corresponding herbicides should be selected for chemical control at different stages. 1. Soil closure treatment after sowing but before emergence. After sowing sesame, use 100 ml of 50% acetochlor emulsifiable concentrate or 200 ml of Dual (72% metolachlor emulsifiable concentrate) per mu, add 50 kg of water, and spray evenly. This can control foxtail grass, crabgrass, shortawn foxtail, goosegrass, and many other annual grass weeds, and also has a certain control effect on many broadleaf weeds propagated by small seeds.
