水稻分蘖末期进行落干烤田,是抑制无效分蘖的重要灌溉措施。烤田可使根系增加48～86％,茎秆矮2～5厘米,植株健壮,抗倒伏,抗病虫害。烤田能改变土壤理化性质,减少有毒物质(HS)含量,提高根系活力。烤田还能使铵态氮和速效磷降低,抑制水稻徒长,从而增加实粒数,提高千粒重。
Rice tiller at the end of dry-up grilled fields, is to inhibit the inefficient tillering of important irrigation measures. Baked fields can increase the root system 48 ~ 86%, short stalk 2 to 5 cm, robust plants, lodging resistance, pests and diseases. Baked fields can change the soil physical and chemical properties, reduce the toxic substances (HS) content, improve root activity. Baked fields can also reduce ammonium nitrogen and available phosphorus, inhibit the growth of rice so as to increase the number of solid particles and improve 1000-grain weight.
