为了说明一些水稻新品种对不同田类土质的适应能力,以便生产上参考应用,故进行了此项试验。一、试验概况 1982年早造与郁南县种子公司、郁南县河口良种场及郁南县连滩公社农业推广站协作,分别在该县河口良种场、县河口种子站、连滩公社范围内选择5种不同理化性质的田类即砂质浅脚田(砂多泥少,漏水漏肥)、山坑冷底田(日照少,冷泉水入田,水温、土温都低,养分供应差)、深湴田(地下水位过高,还原性强,有效磷、钾很少)、黄泥田(粘、酸、浅、瘦)和深肥田进行对比试验,采用3个迟熟品种:“双桂1号”、“辐桂1号”和“桂朝2号”(对照种)。郁南县河口良种场内的深肥田试验,用对比法
In order to illustrate the adaptability of some new rice varieties to different soil types for production reference applications, this experiment was conducted. I. Introduction to the experiment As early as 1982, it cooperated with Yu Nanxian Seed Company, Yunan Hekou Seed Farm and Yunnandongtong commune agricultural extension station, respectively, in the area of Hekoukou seed breeding site, county estuary seed station and Liantan commune Choose five different types of physical and chemical properties of the field that is sandy shallow foot field (sandy mud less, leakage leakage fertilizer), mountain pit cold bottom field (less sunshine, cold spring water into the field, water temperature, soil temperature is low, poor nutrient supply ), Deep 湴 Tian (groundwater level is too high, strong reducibility, available phosphorus, potassium is very small), yellow muddy field (sticky, sour, shallow, thin) and deep fertilizer field for comparative experiments using three late varieties: Gui 1 “,” Gui Gui 1 “and” Gui Chao 2 "(control species). Yu Nanhe estuary thoroughbred field deep fat field test, with the contrast method
