Comprehensive Utilization Of Crop Straw Ecological Research In Shandong District

For a long time， the crop straw has been produced as a by-product of grain， economiccrops， is directly used as fuel for heating， or abandoned. With the development ofeconomy， the fuel value of straw was reduced， and even become an obstacle to thedevelopment of economy. Straw began to be burned or abandoned and resulted in variousenvironmental problems， which attracted the attention of people.HeZe City， the geographical position is superior， has rich resources of crops， strawproblem comes more and more serious. How to make the。problem。 has become the。resource。 in nature， has become the main content of this research topic. The comprehensiveutilization of crop straw is the protection of the ecological environment， the need to conserverenewable resources， but also alleviate the tense situation of feed， fertilizer， fuel andindustrial raw materials， promoting agricultural sustainable development requirements.HeZe area the main crops to wheat and corn. In the receipt of these crops will produce alarge number of straw， utilization of the crop straw. The traditional way of using is used as afuel to be used， some of the individual may be used for biogas production. In recent years，with the improvement of the living standards of the people. Crop straw is used as the fuelutilization is already very few. In order to deal with these straw. A lot of people using in situcombustion way， do not only causes a waste of energy， but also pollute the atmosphere，and even cause a fire， every year to crop harvest seasons will fire accident caused by strawburning some.For the comprehensive utilization of straw， mainly has5ways： one is as anagricultural fertilizer； two is used as feed； three is used as a new type of energy in ruralareas； four is used as industrial raw materials； five is used as base material. But because ofthe restriction and influence of various factors by the traditional concept， technology andpolicy advocacy， crop straw utilization in HeZe area is still in the traditional straw burningand straw as feed.This paper introduces the HeZe straw resources and comprehensive utilization of straw，analyzes the shortage of resources，the problem of excess，discussed the main technical wayfor the comprehensive utilization of straw and restricting factors， and puts forward some suggestions and Countermeasures to promote the comprehensive utilization of straw in HeZecity. Introduced the straw gasification technology， straw silage technology， MechanizationConservation Tillage Technology， rice straw is HI， node stem Zhizhao gas technology，rice and rape production of organic fertilizer technology， wo Ji stalk cultivation of ediblefungi technology， node stem industrial processing technology， rice straw and rice strawpower generation technology to produce bio coal technology10for the development ofHeZe’s crop straw technology， and some techniques in the development of HeZe.According to the present situation of crop straw utilization in Heze area and the presenceof jumbled together, straw burning issues, from straw, straw as feed, straw into fuel and strawas raw materials and other aspects of the comprehensive utilization of straw.
