How to grow summer sesame? A detailed guide to comprehensive high-quality pollution-free cultivation techniques
Sesame is a major oil crop in Linquan County and a leading industry among cash crops, renowned both at home and abroad for its large area, high yield and excellent quality. The "Shenghe" brand sesame oil, "Longmao" brand refined sesame and "Yingxian" brand washed sesame produced by several leading sesame processing enterprises such as "Baoding Grain and Oil Co., Ltd." in the county have obtained China Green Food Grade A standard certification and pollution-free agricultural product certification. In order to improve sesame quality and meet the production requirements of pollution-free agricultural products, on the basis of promoting the results of the "six reform measures for sesame" researched in the county, after many

Detailed Explanation of Pollution-Free Control Techniques for Rice Pests and Diseases
I. Agricultural Control Agricultural control is the foundation for achieving pollution-free control of rice pests and diseases, and its basic principle is to create an environment that favors crop growth and development while disfavoring the breeding of pests and diseases. 1. Increase the application of organic fertilizers and gradually reduce the amount of chemical fertilizers used. In production, relying solely on chemical fertilizers (especially nitrogenous chemical fertilizers) while neglecting the cultivation, composting and use of organic fertilizers is one of the important reasons for the current severe occurrence of rice pests and diseases. Therefore, it is necessary to change concepts, attach importance to developing animal husbandry, planting green manure crops and composting various types of farmyard manure, and establish a new fertilization model based primarily on organic fertilizers and supplemented by chemical fertilizers. In order to increase the sources of organic fertilizer, it is required to plow and sow green manure or other crops in winter to prevent fields from overwintering fallow. Doing so can not only reduce the overwintering base of the striped stem borer (Chilo suppressalis) and sheath blight sclerotia, but also improve the soil. Organic fertilizer is a complete fertilizer and can comprehensively supply the various nutrient elements needed by crops, but it is also a slow-release fertilizer, and most of the nutrient elements it contains cannot be directly utilized by plants; they must first be decomposed by microorganisms into ammonium nitrogen and inorganic salts before they can be absorbed. The early stage of rice growth is precisely the key period when quick-acting fertilizers (especially nitrogen fertilizer) are needed. If the required nutrients cannot be guaranteed, it will inevitably affect normal tillering, resulting in failure to grow vigorously in the early stage and then delayed maturity with excessive vegetative growth in the later stage. Therefore, when increasing the application of organic fertilizer, attention must be paid to resolving the above contradiction between supply and demand in order to achieve safe nitrogen uptake by rice (that is, continuously and evenly supplying nitrogen fertilizer according to the needs of each growth stage, neither too much nor too little, so that rice grows steadily in the early and middle stages and does not senesce prematurely or grow excessively in the later stage). For example: when green manure is the main fertilizer source, first, the total application amount must be controlled, with about 1000 kg of fresh grass applied per 667 sq m, and not too much; second, when sowing green manure, green manure varieties with different degrees of decomposition difficulty must be mixed and sown; third, plowing must be carried out early at the appropriate time to promote the decomposition of green manure. When barnyard manure and cake fertilizer are the main fertilizer sources, efforts should be made to fully decompose them before application, they should be distributed evenly during application, and attention should be paid to intermittent irrigation after transplanting to promote the decomposition of organic fertilizer. Increasing the application of organic fertilizer does not exclude the use of chemical fertilizers; the two should be combined. At the beginning of tillering, apply 50 kg to 100 kg of silicon-manganese compound fertilizer per 667 sq m in a timely topdressing to promote early and rapid growth and steady development of the seedlings, laying a good foundation for pollution-free rice production.

Pollution-free high-efficiency cultivation technology for "rice - mushroom"
In 2002, the Bazhou District Agricultural Technology Station demonstrated and promoted the "rice - mushroom" high-quality and high-efficiency cultivation model in more than 20 townships including Enyang and Huacheng, obtaining a per-mu (1 mu = 1/15 hectare, the same below) output value of 7148.56 yuan, an increase of 6297.56 yuan per mu compared with the wheat-rice double cropping system, a 7.4-fold increase. Practice shows that this model has the characteristics of increasing rice yield, improving soil fertility, high mushroom yield, tender texture and delicious taste, and simple operation. It is also a good way for farmers to generate tax revenue, increase income, and get rich quickly. I.
