烤烟新品种NC102配套栽培技术研究

为促进优质烤烟新品种NC102在云南省主要烟叶产区的推广种植,2012年在石林县利用L27(313)正交试验设计开展了美引品种NC102的配套栽培技术措施研究。结果表明,在本试验设置的4个处理因素中,施氮量是最主导因素。通过对NC102的经济性状、内在化学成分和感官质量评价等性状的综合分析,最终获得了NC102的最佳栽培技术措施组合。最佳施氮量为每667m2 7.0kg,株距为0.55~0.6m,留叶数为20~22片·株-1,打顶时期为扣心打顶或开花打顶。     

云岭水果笋高产栽培技术研究

试验研究了不同地区、不同栽培措施对高氏甜龙竹发笋及笋产量的影响。结果表明：在云南勐海县、普洱市海拔1 300~1 700 m，重庆市武隆区、四川宜宾市等地海拔600 m以下的地区适合栽种笋用高氏甜龙竹；高氏甜龙竹栽植适宜的株行距为2 m×4 m，栽种时，以每丛留3~4株母竹、米径控制在4~8 cm为宜；在母竹高2.5 m处封顶可促进枝叶生长和笋芽萌发，增加笋产量；施肥、浇水、竹丛覆盖和剥土晒蔸等措施均能提高笋产量。     

关于苗木栽培技术的初步探讨

随着人民群众对生活环境和绿化水平要求的不断提升,苗木行业的市场发展可谓越来越蓬勃,行业前景也是越来越光明。因此与之相关的苗木栽培技术也受到越来越多人的关注。但目前我国苗木行业在栽培技术方面仍存在一定程度的欠缺和不足。基于此,着重对苗木栽培前期的选地、选苗等环节及栽植过程中的技术问题进行分析,希望对今后的工作有所借鉴。     

Soil available potassium affected by rice straw incorporation and potassium fertilizer application under a rice–oilseed rape rotation system

Data from 147 field trials were collected to study the influence of straw incorporation on soil potassium (K) under an intensive rice–oilseed rape rotation system, while pot experiments were conducted to evaluate the effects of rice straw incorporation on soil K availability. A significant correlation was observed between the soil available K and the relative yield (RRY) and the relative K uptake (RKU) of oilseed rape, with R² values ranging from 0.07 to 0.08 and from 0.10 to 0.11, respectively, when data were fitted to a logarithmic equation model. In approximately 30% of trials, RRY reached 90%, while soil test available K values were below the critical limit, indicating that soil K values at the time of sampling (within 1 week of rice harvest) underestimated the actual soil K supply capacity. The pot experiment results showed that soil available K was affected by straw incorporation and soil type in the fallow period. The NH₄OAc‐K and NaBPh₄‐K concentrations of soils increased at first, and then, plateaued after 28 days. Straw incorporation significantly influenced the critical soil K concentration, which is important for making accurate K fertilizer recommendation. These results suggested that straw K should be seriously considered in making K fertilizer recommendations. Extending the sampling time from 1 to 3 weeks after the harvesting of rice to stabilize the effects of straw incorporation may help achieve a more accurate evaluation of soil available K.
