High-yielding Cultivation and Fertilization Technology of Lvhan No.1 in Angola

[Objective] The aim was to research high-yielding cultivation and fertilization technology for Lvhan No.l, a new Chinese rice cultivar, in Angola. [Method] In rainy season of 2012, high-yielding cultivation and fertilization technology of Lvhan No.l, a new cultivar of earlier ripe and drought resistant rice, was researched in CATETE farm of Luanda suburb with pot experiment method. [Result] In CATETE farm, Lvhan No.1 rice were directly sown in black clay and the rice can be significantly improved in plant height, grain weight of single plant, biological yield of single plant, ear length, total grain number per ear, number of filled grain per ear and thousand seed weight, as well as economic coefficient and ratio of grain to straw, if applied with base fertilizer made up of DAP （N：P2Os=14：43）, or compound fertilizer of N, P and K （N：P2Os：K^O=15：15：15） and with Duannai fertilizer and ear-grain fertilizer made up of urea. If DAP is taken as base fertilizer, the optimal quantity is 300 kg/hm2. If compound fertilizer of N, P and K is taken as base fertilizer, the optimal quantity is 450 kg/hm2, but urea at 75 kg/hm2 should be applied as Duannai fertilizer and ear- grain fertilizer, respectively, on time. [Conclusion] The research provides technical ref- erences for planting of Chinese rice cultivars in Angola.

耐旱水稻新品种“绿旱1号”节水特性

为探索绿旱1号的节水特性,比较了绿旱1号及原始受体＂6527＂在有水层管理和无水层旱管条件下的生育期和经济性状。结果表明,在无水层较有水层节水67.4%的条件下,2个品种生育期均延长2~5天。在无水层旱管方式下,＂绿旱1号＂千粒重、结实率、株高、有效穗降幅较小,但均未达显著水平,而原受体＂6527＂小区产量、穗总粒数、理论产量、穗实粒数降幅最大,均超过25%,且均达极显著水平（P〈0.01）。＂绿旱1号＂在节水栽培条件下,表现产量稳定、节约能源、减少环境污染等优点。
