在山区冷烂锈田实行水稻垄作,能改善水稻生态条件,改良土壤理化性状,提高土壤肥力。经几年试验,垄作比平作田水温提高1℃,泥温提高0.3～1℃;垄作后土壤变疏松,容重降低,<5mm团聚体明显增加,改善了土壤通透性,促进微生物活动,协调了土壤水、肥、气、热状况,从而促进水稻早生快发,有效穗和穗粒数增多,增加千粒重、提高水稻单产。垄作水稻产量一般较平作增高11.5～78％,有的成倍增长。说明垄作是改良山区冷烂锈田、促进水稻增产的一大有效措施。
The implementation of paddy planting in the cold and rotten fields in mountainous areas can improve the ecological conditions of rice, improve the physical and chemical properties of the soil and increase the soil fertility. After several years of experiments, the temperature of ridge-cropping field increased by 1 ℃ and the temperature of mud increased by 0.3 ~ 1 ℃. After ridge cultivation, the soil became loose and its bulk density decreased. The agglomeration of <5mm increased obviously, which improved the soil permeability and promoted the microbial activity. The soil water, fertilizer, gas and heat conditions, so as to promote rapid early rice growth, effective panicle and grains per spike, increase 1000-grain weight and improve rice yield. The yield of ridge-growing rice is generally 11.5% ~ 78% higher than that of flat land, and some of them are doubled. This shows that ridge cultivation is a great effective measure to improve the cold rotten rust field in mountainous areas and promote the yield increase of rice.
