Research On The Application Result Of System Fertilizer Recommendation Technology In Shanxi Agriculture Comprehensive Exploitation Zone

The core of System Fertilizer Recommendation Technology is to make balance fertilization pertinently according to the amount of the soil nutrition, the nutrition needing regulation of corn and target production. The technology can not only increase the production but also can improve the economy benefit. Using system research method, this research is to make use of System Fertilization Technology in Shanxi Agriculture Comprehensive Exploitation Zone. The essay compares System Fertilizer Recommendation Technology with farmer's traditional fertilizer method by using system Fertilizer Recommendation Technology and monitoring field nutrition on the following three main crops: wheat, corn and broccoli. The result is growing conditions (weight of a hundred seeds, fringe length, fringe seeds, seeds and nitrogen amount in stems), quality (the content of protein and starch, etc) and production of the crops are increasing at different level. And at the same time, it brings notable economic benefit correspondingly (The cost is lower by 138.97Yuan per ha, and the economic benefit is upper by 871.22Yuan per ha) . Compared with traditional fertilization, the amount of nitrogen, phosphorus, potassium, etc is close to the needs of crops. The soil nutrition keeps balance generally with higher production. Thus, this method not only saves fertilizer investment and adds producing benefits getting high production and high benefit, but also keeps the balance of the soil fertilization. As a result, it avoids soil poverty, resource waist, the possibility of nitrogen pollution to ground water and many other similar problems. The science and pertinency and high production, high benefit and good quality are characteristics of System Fertilizer Recommendation Technology. and these characteristics are just one of the important promotion method. It has significant meaning to increase science content of agriculture comprehensive exploitation zone, increase production, improve quality, lower environment pollution and promote agriculture sustainable development by using System Fertilizer Recommendation Technology to manage soil nutrition and fertilization in agriculture comprehensive exploitation zone. The method is starving for promotion widely.
