水稻旱作覆盖栽培具有提高地温,保持土壤水份,减少肥份流失,促使土壤疏松等特点。覆盖栽培还有助于改变防碍水稻旱种的不良气候条件。在日本宫城县,旱作覆盖栽培水稻每公亩获得400公斤产量是不困难的。然而,由于生育旺盛,茎高叶茂,籽粒充实,就容易发生倒伏。因此,覆盖栽培造成减产的原因,大多数是倒伏所致。可见,在覆盖栽培中倒伏是个大问题。本文拟从旱作水稻地膜覆盖栽培试验结果谈防止倒伏的一些方法。
Rice cultivation with dry cultivation has the characteristics of raising the temperature, keeping the soil moisture, reducing fertilizer loss, prompting the soil loose. Covered cultivation also helps to change the unfavorable climatic conditions that prevent dry farming of rice. In Miyagi prefecture in Japan, it is not difficult to obtain a yield of 400 kg per mu for dry cultivation of cultivated rice. However, lodging is prone to fertility due to strong fertility, high leaf stems and abundant kernels. Therefore, most of the reasons for the decrease in production due to cover cultivation are due to lodging. Can be seen in the cover cultivation lodging is a big problem. In this paper, some measures to prevent lodging from the dry film mulching rice cultivation test results.
