不同施肥方式对芝麻生长发育的影响

通过田间小区试验，研究了常规施肥、分层一次性施肥、一次性深层施肥、一次性深施＋ 风化煤（ 吸附剂） 对芝麻生长发育的影响，结果表明：一次性深层施肥有利于芝麻的生长发育。对于不同的施肥方式，芝麻在苗期的长势差异不大，而在初花期后，各阶段的长势及产量均表现为：一次性深施＋ 风化煤＞ 一次性深施＞ 分层施肥 ＞ 常规施肥。其中一次性深施加与不加风化煤差异很小

Effects of Different Fertilization Modes on the Growth and Development of Sesame

Plot experiment with four treatments ,i. e. conventional manuring (CM),layer by layer manuring for once (LBLM), subsoil manuring for once (SM) and subsoil manuring with efflorescent coal (adsorbent ) for once (SMWEC) was designed to study the effects of different fertilization modes on the growth and development of sesame. Results showed that SM and SMWEC were favourable for the growth and development of sesame; The growth vigour of sesame at seedling stage had little difference among different fertilization modes;Since initial flowering stage ,the growth vigour and yield of sesame were in the following order :SMWEC>SM>LBLM>CM,but the difference between SMWEC and SM was much less.
