水稻穴播同步侧位深施肥技术试验研究

根据水稻种植的农艺要求,在同步开沟起垄水稻精量穴播技术的基础上进一步提出了一种水稻穴播同步侧位深施肥技术。调查了在不同种植方式条件下不同品种的水稻根系在稻田中的分布情况,根据根系的分布情况研究了深施肥技术参数,确定了深施肥深度以不超过10 cm为宜,研究了培杂泰丰、玉香油占2种品种水稻施入0~5 cm土层与5~10 cm土层中的肥料比例关系。试验结果表明华南农业大学研制的同步开沟起垄侧位深施肥水稻精量穴播机能满足水稻穴播同步侧位深施肥技术的要求,可以作为实施水稻穴播同步侧位深施肥技术的载体。生产试验表明:水稻穴播同步侧位深施肥技术具有增产、节本的效用。在同等的施肥条件下,机械播种及深施肥处理的...

Summary:根据水稻种植的农艺要求,在同步开沟起垄水稻精量穴播技术的基础上进一步提出了一种水稻穴播同步侧位深施肥技术。调查了在不同种植方式条件下不同品种的水稻根系在稻田中的分布情况,根据根系的分布情况研究了深施肥技术参数,确定了深施肥深度以不超过10 cm为宜,研究了培杂泰丰、玉香油占2种品种水稻施入0~5 cm土层与5~10 cm土层中的肥料比例关系。试验结果表明华南农业大学研制的同步开沟起垄侧位深施肥水稻精量穴播机能满足水稻穴播同步侧位深施肥技术的要求,可以作为实施水稻穴播同步侧位深施肥技术的载体。生产试验表明:水稻穴播同步侧位深施肥技术具有增产、节本的效用。在同等的施肥条件下,机械播种及深施肥处理的有效穗、穗平均实粒数、结实率均高于机械播种人工撒施肥和人工撒直播人工撒施肥,增产418.5~957 kg/hm2,增幅5.86%~13.41%。该文研究可为深施肥机具的设计提供参考依据。
Bibliography:Deep fertilizing is a high efficiency fertilization method in rice fields. In order to realize deep fertilizing, according to the requirement of rice planting, a synchronous side deep fertilizing technique is developed on the base of a precision rice hill-drop drilling technique. By ditching, ridging, deep fertilizing, and seeding joint operations, the fertilizing ditch openers prescribe fertilizing ditches, and the fertilizer apparatus puts fertilizers into the fertilizing ditches which are between two seeding ditches, to provide fertility of the necessary growth for rice in the two seeding ditches. At the same time, the fertilizing ditches are covered by the skateboard. After covering, fertilizers can reduce the loss due to volatilization, denitrification, and leaching. And then the seeding ditch openers prescribe seeding ditches, and the seed-falling devices take rice into the seeding ditches, at the same time the water ditch openers prescribe water ditches, and the water in the water ditches will be provi
