Method for Making River Crab Feed from Potatoes
Using potatoes to make river crab feed has the advantages of widely available raw materials, low cost, good palatability and rich nutrition, and river crabs like to eat it and grow readily. At the same time, this feed-making method is relatively simple; it can be produced on a large scale with machinery or made by hand, so potato crab feed has broad application value. The key processing and feeding techniques are introduced below for the reference of aquaculture farmers. Process flow: material selection -> cleaning -> cutting into pieces -> steaming -> crushing -> ingredient mixing -> shaping -> drying. Processing techniques: (1) Material selection. Choose potatoes free of pests and diseases, without sprouting,

Hybrid late japonica rice restorer lines successfully bred in the Yangtze River Basin
Through the efforts of experts from the Shanghai Academy of Agricultural Sciences, the "Yangtze River Basin hybrid late japonica rice restorer lines - Shenhui 254 and Shenhui No. 1" were successfully bred and utilized. This project was awarded first prize for scientific and technological progress by the Shanghai Municipal Government this year. The key to applying hybrid late japonica rice in production in the Yangtze River Basin is to breed excellent late japonica-type restorer lines. This project used intermediate materials between indica and japonica subspecies as bridge parents, introduced indica restorer genes into late japonica rice varieties, adopted convergent crossing and systematic selection, and gathered the excellent base

Spring cotton production technical guidance: how to manage the Yellow River basin cotton region
Raising seedlings and transplanting Simplified seedling raising and transplanting. First, choose a good seedling-raising site. It should be high-lying, sheltered from the wind and facing the sun, with convenient access to water and transportation. Second, prepare materials. Use seedling-raising substrate plus clean river sand to make a seedbed or fill plug trays, replacing nutritional pots, and prepare enough materials for 500 seedlings per sq m of seedbed. Third, sow at the right time...
