我所从1980年开始,在安塞县马家沟流域内的李家圪塔生产队和延安市上砭沟大队,作为重点试验基点,进行了草田带状间作和草田轮作试验示范。通过两年的试验,初步证实用草木栖进行草田轮作,在陕北黄土高原丘陵山区潜力很大,很有发展前途,是促进山区向农牧业发展的途径之一。 Since 1980, we have carried out experiments and experiments in the Caragana intercalation and the Caotian rotation in the Lijiaba tower production team in the Majiagou drainage area of ​​Ansai County and the Shangyougou Brigade in Yan’an City as the key test bases. After two years of experiments, it was tentatively confirmed that the rotation of grassland by grass habitat was promising and promising. It is one of the ways to promote the development of agriculture and animal husbandry in the mountainous area.
