简要介绍了长根菇生物学特性以及长根菇反季节栽培适宜制袋日期、简易保温增温出菇房的搭建和栽培管理要点.

In order to explore the impact of substrates on Pleurotus pulmonarius's yield and quality , different treat-ments of substrate preparation , sterilization and other conditions were set up .The results showed that the physical-chemical characters of substrates which were placed for more than 4 hours after bagging would deteriorate , and had a negative impact on mycelia and fructification growth .After sterilization under atmospheric pressure for 1, 2, 3, 4 and 5 times, the bulk density and electrical conductivity ( EC) index of substrates increased , but the aeration porosi-ty, moisture content and pH value decreased according to the increasing sterilization times .And the time of full bags of hyphae were 42, 49,56,63 and 70 d, respectively.The biological conversion were 52.26%, 45.85%, 45.19%, 40.10%and 40.91%, respectively , which indicated that the number of sterilization times had a negative effects on hyphae nutrition and reproductive growth .It can be concluded that substrates can maintain good physical and chemi-cal properties and were beneficial for high-quality and high-yield of Pleurotus pulmonarius when they were sterilized under atmospheric pressure at 4 h after bagging , at 100 ℃for 10 h.

三种封口材料在金针菇菌种瓶上的应用结果表明:无菌透气膜封口的菌种菌丝满瓶时间介于棉花塞、聚丙烯膜两者之间,比用棉花塞慢2 d、聚丙烯膜封口快10 d;常温培养20 d,菌丝健壮,杂菌污染率比棉花塞低3%;菌种扩接栽培袋成品率达99.5%,平均产量比棉花塞菌种增产13.4%,出菇子实体发病率比棉花塞菌种低2.3%.

<正>板栗是浙西山区的主要经济作物,每年都有百万吨板栗壳废弃堆积。为了充分利用当地资源,延伸产业链,提高农业附加值,近年来,本所利用板栗壳生料进行了平菇栽培试验,效果良好,生物转化率可达100%~120%。现将该高产栽培技术总结如下。1栽培季节安排根据平菇生料栽培的生物学特性,结合本地区气候条件,一般安排10月中旬至12月下旬播种,

Theoretical research has proved that FDI had a positive effect on economic growth,but has little focus on the mechanism between them.This paper gives three examinations under endogenous growth framework:(1)The casual link between FDI and economic growth;(2)The main factors affecting economic growth;(3)The correlation between FDI and these main factors.Results show that physical capital,technological advances,industrial structure change and trade are the main factors of affecting economic growth,and FDI in human capital is not significant.The link between FDI and economic growth in Zhejiang Province is not consistent with endogenous growth path.

The relationship between FDI and economic growth has always been a controversial academic issue.In order to understand the conduction path between FDI and economic growth comprehensively and accurately,we had an empirical analysis in a single-sector endogenous growth model of economic growth.We also conducted a correlation test between FDI and other affecting factors.Based on these analyses,we put forward some suggestions for absorbing FDI and industrial upgrading.

FDI的技术外溢效应一直是国内外经济学理论关注的一个焦点,越来越多的研究表明FDI的外溢效应和东道国自身的环境和条件相关。其中金融发展在技术外溢效应中的作用是目前较为前沿的一个研究领域。本文对国内外学者在该领域中的研究成果进行系统的概述和评价,以期为国内后续的相关研究提供一些有益的启示。
