一、陆稻点播的好处 1.有利于保护森林,促进林业的发展。七十年代初,腾冲县清河大队每年种火烧地陆谷200多亩,需枝叶架柴4000多担,耗费林木不少。用点种取代火烧地后,树木得到了保护。已退耕还林300多亩,还为大牲畜提供了部份草场,对发展畜牧业及水土保持都是有利的。 2.固定了耕地,提高了土地利用率,培肥了地力。过去200多亩火烧地4—5年轮种一次,实际上占着千亩土地。火烧是4—5亩当一亩,点播一亩就是一亩,土地利用率提高了。据化验分析,烧过的地全磷、速效磷、速效钾虽有增加,但有机质、全氮、碱解
First, the benefits of land-based on-demand broadcast 1. Conducive to the protection of forests, and promote the development of forestry. The early seventies, Tengchong County Qinghe brigade every year burning 200 acres of land and land valleys, wood need to be more than 4000 branches and leaves, spent a lot of trees. With some kind of seed to replace the fire, the trees have been protected. The area of more than 300 mu has been returned to farmland, and some pastures have also been provided for large livestock, which is beneficial to the development of animal husbandry and soil and water conservation. 2. Fixed arable land, improve land utilization, fertility of fertility. In the past 200 mu of land burned 4-5 years rotation, in fact, occupy acres of land. When the fire is 4-5 acres when an acre, on-demand one acre is acre, land utilization increased. According to laboratory analysis, burned ground total phosphorus, available phosphorus, available potassium although increased, but organic matter, total nitrogen, alkaline hydrolysis
