各种作物对土壤条件要求的严格程度各不相同,有的作物如小麦、水稻、甘薯等对土壤条件的适应性较广,有的作物如芝麻、烟草等则对土壤条件的要求比较严格。关于农作物对土壤条件的要求与适应性能的研究工作,报导的较少。本文拟就我国有关芝麻栽培的一些调查研究资料对芝麻的土宜作一些分析研究,借供有关同志参考。 一、芝麻与土壤条件 芝麻在我国从南到北虽均有种植,但对土壤条件的要求则比较严格,这与它本身生长期短、籽粒小、根系入土浅,耐旱耐涝力差等生物学特性有密切关系。 土壤质地条件是影响芝麻生长发育的重要因素。芝麻籽粒小,幼苗出土力弱,生长较慢。所以,要求质 Various crops have different strict requirements on soil conditions. Some crops such as wheat, rice and sweet potato are more adaptable to soil conditions. Some crops such as sesame and tobacco have strict requirements on soil conditions. Less work has been reported on the requirements and adaptation of crops to soil conditions. This article intends to sesame cultivation in China on some of the research data on the sesame soil should make some analysis, for reference by the relevant comrades. First, the sesame and soil conditions Sesame in our country from south to north, although both planting, but the soil conditions are more stringent requirements, which with its own short growth period, small seeds, roots into the soil shallow, poor drought tolerance Biological characteristics are closely related. Soil texture conditions are important factors affecting the growth and development of sesame. Small sesame seeds, seedlings unearthed weak, slower growth. So, ask for quality
