云南板栗早实性研究

实生板栗幼树从定值后第3年开始地径和树高生长超过嫁接苗。平均地径、树高和冠幅以永仁实生板栗最大。实生板栗早实性仅表现在形成雄花序和雌花簇，定值后第4年所有实生板栗幼树所结的球苞均为空苞，并以永仁实生板栗平均单株球苞数量多。达到104．6个。

Responses of fruit growth,quality, and productivity to crop load in apple cv. Ultra Red Gala/MM111

The effects of three crop load densities (4, 6 and 8 fruit per cm² of the cross-section of each tree branch, BCSA) on fruit growth, yield, fruit quality and vegetative growth were studied in apples (Malus × domestica Borkh) Ultrared Gala/MM111, from the fourth leaf (2006–2007 season) to the sixth (2008–2009 season). The maximum fruit growth rate was reached between 90 and 108 days after full bloom (DAFB), with values above 2.6 g day⁻¹. Accumulated yields to the sixth leaf reached 181, 157 and 123 Mg ha⁻¹ in the high, medium and low crop loads, respectively. Mean fruit weight decreased with increasing fruit crop load but the yields of fruit weight over 194 g were similar in all crop loads; the highest crop load exceeded the lowest crop load by 18.8 and 27.5 Mg ha⁻¹ of fruit weight of more than 172 and 154 g, respectively. The yields of harvested fruit exceeding 75% with red coloring did not show major differences, while fruit classified as 50–75% with red coloring were less common in the low crop load. No major differences were found at the end of the study in vegetative growth in the different seasons, nor in plant size. The reduction in mean fruit weight and in the percentage of fruit with good coloring was compensated by the increase in yields, thus not resulting in an effective reduction in the quality of the harvested fruit. The level of plant development reached with a semi-vigorous rootstock and high fruit loads allowed obtaining high fruit yield earlier and of good quality.     

利用休眠控制河蟹性腺早熟的养殖试验

该项试验是针对近年来在河蟹养殖中幼蟹（扣蟹）性腺早熟提出的研究课题。根据顾景龄等“河蟹生长规律及性腺早熟控制的研究”证明：幼蟹性腺早熟的主要原因是６月至７月底期间，幼蟹蜕壳过频，生长过快所致、为控制幼蟹的性腺早熟，我们经过多年的试验研究，探索出利用“休眠”控制其早熟的养殖方法，并于１９９３年６月至９月３０日，在天津宁河县试验林场６． ６７ｈｍ２的河蟹精养池塘进行了生产性试验，在 ６月 １０日至 ８月 ５日期间，停止投饵、换水，使幼蟹进入休眠状态，８月５日以后，驯化投喂人工配合饵料，并严格控制水质，到９月３０日，幼蟹平均个体重达 ２３．９ ｇ，与对照组平均体重２５． ７ ｇ相近似，试验组早熟率不超过 ４％，而对照池（３．３３ ｈｍ２）几乎全部早熟。因此可以说这是一种控制幼蟹早熟简单而有效的方法。     

葡萄新品种郑艳无核在广西南宁的引种表现 及一年两收栽培技术

为了充分利用广西及南方地区的温光资源,引种适合一年两收的无核、红色、具香味葡萄新品种。本试验引进郑艳无核葡萄新品种在广西南宁种植,观察其植物学特性、物候期、生长结果习性、果实性状及抗病性等表现,并研究其一年两收栽培技术。经过4年的引种观察,郑艳无核葡萄在广西南宁可成功实现一年两收,表现为红色、无核、早熟、果穗中等、不易裂果、着色均匀、有香气、稳产等特点。4年引种观察期间,一茬果每667m2最多为708.14kg,二茬果每667m2最多为578.02kg;一茬果可溶性固形物含量最高为22.97%,二茬果可溶性固形物含量最高为23.71%;一茬果在6中旬到月末果实完全成熟,二茬果在11月底到12月初果实完全成熟。郑艳无核葡萄在广西南宁引种表现优良,适合在广西南宁及气候类似地区在避雨条件下进行一年两收栽培。
