【摘要】 研究了稻田丝状藻类与土壤肥力的关系,经试验观察表明:当稻田丝状藻类大量生长时,与水稻争肥而引起水稻减产;若将丝状藻类掩埋在稻田里,水稻的减产比将这些藻类捞出丢掉要少些.水稻收获后播种小麦,掩埋有藻类的比将藻类捞出丢掉的产量有显著增加.综合稻麦两季的产量,发现掩埋藻类的比未埋藻类的稻田的总产量更高.更多还原

【Abstract】 The effect of filament algae in rice field on the soil fertility was studied by the pot culture method. The results were as follows.The output of rice was obviously reduced in the pot algae grown. The output of rice was about equal to that of the check if the algae were dredged and buried in soil of the pot. Wheat was planted after rice was harvested the output of wheat in those pots was much more than that of the check. The author suggest that the algae may be burried in field when they grow adequately to improve soil fertility.更多还原
