为综合开发水体生态农业,开辟种稻新领域,在前人研究的水面无土种稻的基础上,1991年笔者首先进行水面无土培植再生稻试验,并获得小区试验的成功。现介绍如下: 试验在我市沙县虬江乡灵源村进行。水体面积0.3亩(村门口池塘,养鱼30尾)。水面无土培植再生稻试验面积0.036亩。选用早稻成优77,中稻汕优63两个组合,浮体以当地取材容易、成本低、浮力较好的芦苇秆为材料,编织成长1.5米,宽1.0米,并把它放进池塘水中。3月中旬旱地薄膜育秧,秧龄40多天移栽,人站在池塘中,把带土的秧苗插在浮体上,密植规格16.5厘米×16.5匣米。头季稻共追肥12次,每次折亩
In order to comprehensively develop water ecological agriculture and open up new areas for rice cultivation, based on the waterless soilless rice researched by predecessors, in 1991, the author firstly carried out soilless soil cultivation and regeneration rice experiment and obtained the success of plot experiment. Are introduced as follows: Test Shaxian Quxiang Township Lingyuan village. Water area of 0.3 acres (village gate pond, fish 30). Soil test soilless cultivation of regenerative rice area of 0.036 acres. The combination of early rice Chengyou 77 and middle rice Shanyou 63 was used. The floating body was woven with 1.5-meter-long and 1.0-meter-wide of reed stalks which were easy to obtain locally and with low cost and good buoyancy and put it into pond water. In mid-March dry film thinning seedlings, transplanting more than 40 days of seedling age, standing in the pond, the soil with seedlings inserted in the floating body, close planting specifications 16.5 cm × 16.5 box meters. A total of top crop of rice topdressing 12 times, each fold acreage
