在香梨3年生幼林园内,进行了常规沟植、渠道内外二侧种植的土壤贮水量和树木新梢生长量、叶片生长状况变化的测定。结果表明,渠外行的土壤贮水量和生长状况均好于沟植和渠内行。揭示了影响树木生长的不同灌溉条件的土壤水分状况和过程。提出了生产中要提倡渠外行栽种香梨,保持沟植香梨,放弃渠内行栽植香梨的生产模式理论依据。
In the 3-year-old young plantation of Xiang pear, the soil water storage, the growth of new shoots and the change of the leaf growth of the conventional planting and planting, the planting on both sides inside and outside the channel were measured. The results showed that the water storage capacity and growth status of the ditch outside the canal were better than that of the ditch plant and the canal. The soil moisture status and process of different irrigation conditions affecting the growth of trees were revealed. Proposed in the production should promote the cultivation of fragrant pear outsiders, to maintain ditch planting fragrant pear, abandon the canal planting pear production model theory basis.
