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.

Key Techniques for Intercropping Sweet Potato with Sesame
Sweet potato is a vining crop with a low light-receiving position. When intercropped with sesame, which has a high light-receiving position, it forms a well-layered crop community, thereby improving light energy utilization. Generally, without reducing sweet potato yield, it increases sesame seed income by 30-40 kg per mu. This planting method is suitable for all sesame-producing regions. 1. Planting methods (1) Sweet potato is cultivated with plastic film mulching. When preparing the land, form ridges with a height of 10-12 cm, a top width of 60 cm, a bottom width of 80 cm, and a ridge spacing of 40 cm. Sweet potato seedlings are raised 7-10 days earlier than usual according to conventional practice.

Hangzhi No.1, a new sesame variety, is the only variety in China developed through spaceflight technology.
Variety origin: "Hangzhi No.1" originated from the key project "Ninth Five-Year Plan Crop Spaceflight Technology Breeding" supported by the Ministry of Agriculture. In 1996, parent sesame seeds provided by the Oil Crops Research Institute of the Chinese Academy of Agricultural Sciences were carried aboard China's 17th recoverable satellite, stayed in space for 15 days and then returned to Earth. Since 1997, continuous multi-year ground selection was carried out. Through comparative trials on genetic stability, yield, quality and resistance, it was significantly superior to the control. From 2001 to 2002, it was advanced to the national sesame

Clever methods of using growth regulators to promote the recovery of sesame
During the flowering and capsule-setting stage of sesame, vegetative growth and reproductive growth proceed together, and the following key points should be mastered in field management. Reasonable topdressing: topdressing at the flowering stage can promote flower bud differentiation in sesame. Methods such as broadcasting nitrogen fertilizer and foliar spraying of phosphorus-potassium fertilizer and boron fertilizer can be used. For fields with good soil fertility retention and supply capacity, applying urea once at the early flowering stage is sufficient,...
