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.

Key Technical Points for Spring Sesame Cultivation with Plastic Film Mulching
Plastic film mulching cultivation can bring sesame yields to over 150 kg per mu, and some can exceed 200 kg, so film mulching is an effective cultivation measure for achieving super-high sesame yields. The specific techniques are introduced as follows: 1. Seed selection and timely early sowing: After plastic film mulching, the effective growth period of sesame is extended. Therefore, mid-to-late maturing excellent sesame varieties with waterlogging tolerance, disease resistance, and high yield potential should be selected, such as Yuzhi No. 5, No. 7, No. 8, and sesame hybrids. Early sowing is suitable, with a sowing period from the end of April to early May, to fully utilize the growing season and increase sesame yield. 2. Land preparation

Land preparation and sowing methods for spring sesame and summer sesame
Spring sesame should adopt the "plowed furrow slice" method. The so-called "plowed furrow slice" means that after the previous crop is harvested, fertilizer is applied, the soil is plowed and harrowed, and then sesame is sown. The advantages of "plowed furrow slice" are: it can turn the soil and loosen it, increasing soil temperature; bury the base fertilizer, improving fertilizer efficiency; reduce weeds, making intertillage convenient; and the soil has good aeration, which can improve the soil's water storage and fertilizer retention capacity. Therefore, planting "plowed furrow slice" sesame is a key measure for increasing yield. For summer sesame, "iron stubble" sowing should be advocated, with rough sowing and careful management. "Iron stubble" sowing means that after the previous wheat crop is harvested, there is no further plowing, plowing or harrowing; as long as it is raked
