【摘要】：本文利用陜西、山西兩省黃土高原地區(qū)476戶農(nóng)戶的實(shí)地調(diào)查數(shù)據(jù),運(yùn)用樣本選擇模型分析了黃土高原農(nóng)戶保護(hù)性耕作技術(shù)的采用與采用程度及其影響因素。研究發(fā)現(xiàn):(1)整套采用保護(hù)性耕作技術(shù)體系的農(nóng)戶比例很小,其中,對(duì)秸稈覆蓋和少耕免耕播種技術(shù)的采用率較高,而對(duì)深松和病蟲(chóng)草害綜合防治技術(shù)的采用率較低。(2)戶主年齡較小且受教育程度較高、對(duì)保護(hù)性耕作技術(shù)認(rèn)知度較高的風(fēng)險(xiǎn)偏好型農(nóng)戶,不僅傾向于采用保護(hù)性耕作技術(shù),而且傾向于采用多項(xiàng)保護(hù)性耕作的核心技術(shù);農(nóng)業(yè)收入比重較低、家庭收入水平較高的農(nóng)戶對(duì)保護(hù)性耕作技術(shù)的采用程度較高,耕地細(xì)碎化程度則抑制了農(nóng)戶保護(hù)性耕作技術(shù)采用程度的提高。(3)農(nóng)戶間的頻繁交流、網(wǎng)絡(luò)學(xué)習(xí)和政府向農(nóng)戶提供補(bǔ)貼對(duì)農(nóng)戶保護(hù)性耕作技術(shù)的采用及采用程度均有顯著的促進(jìn)作用;而參加保護(hù)性耕作技術(shù)培訓(xùn)、作業(yè)機(jī)械的便利性以及作業(yè)效果僅對(duì)農(nóng)戶保護(hù)性耕作技術(shù)的采用有正向作用。
[Abstract]:Based on the field investigation data of 476 households in the Loess Plateau of Shaanxi and Shanxi provinces, this paper analyzes the adoption and adoption of conservation tillage technology and its influencing factors in the Loess Plateau by using the sample selection model. The results show that: (1) the proportion of farmers adopting conservation tillage technology system is very small, among which, straw mulching and no-tillage sowing technology are adopted more frequently. However, the adoption rate of integrated control techniques for deep pine, insect, insect and insect pests was lower. (2) the households with lower age and higher education level and higher recognition of conservation tillage technology were not only inclined to adopt conservation tillage technology. And it tends to adopt the core technology of conservation tillage; The proportion of agricultural income is low, the household income level is higher, and the degree of fine fragmentation of cultivated land restrains the increase of the adoption of conservation tillage technology. (3) frequent communication among farmers. Network learning and government subsidies to farmers have a significant role in promoting the adoption and adoption of conservation tillage techniques. In the training of conservation tillage technology, the convenience of working machinery and the effect of operation only have positive effect on the adoption of conservation tillage technology of farmers.
