Detailed Explanation of Technical Specifications for Pollution-Free Pesticide Use in Potatoes
1. Cultivating strong seedlings free of pests and diseases (1) Seed potato selection: For pollution-free potatoes, seed potatoes that are pest- and disease-resistant, disease-tolerant, and free of pest and disease damage should be selected. A seed-production field free of pests and diseases should be strictly established, and pest- and disease-free small whole seed potatoes should be cultivated in the pest- and disease-free seed-production field. The small whole seed potatoes kept for seed should be selected during storage. After the seed potatoes are taken out of the cellar, they should be strictly selected, using young and mature tubers as seed, and eliminating tubers with undesirable traits such as irregular shape, rough and aged skin, protruding eyes, and dull skin color. The quality of seed potatoes shall meet the requirements for improved grain crop varieties or above under GB8079-1987.

Detailed Explanation of High-Yield Soybean Cultivation Technical Specifications
Soybean is a major oil crop in our province. Developing soybean production is of great significance for improving people's food composition, developing animal husbandry, and improving soil fertility through crop rotation. From the actual situation of our province, soybean production mainly relies on increasing per-unit yield to increase total output. To achieve the target of over 200 kg per mu, it is necessary to liberate soybean from corn fields, because intercropping and mixed cropping of soybean with corn is one of the reasons for the low per-unit yield of soybean in our province, so clean planting of entire fields should be promoted; second, actively promote high-yield cultivation techniques centered on equidistant sowing, with increased application of farmyard manure
