摘要：探索防蟲(chóng)網(wǎng)覆蓋栽培技術(shù)對(duì)網(wǎng)室環(huán)境因子和砂糖橘冬稍生長(zhǎng)的影響。對(duì)12月份40目防蟲(chóng)網(wǎng)內(nèi)外環(huán)境因子、害蟲(chóng)和冬梢性能進(jìn)行了檢測(cè)，結(jié)果顯示，40目透光防蟲(chóng)網(wǎng)防蟲(chóng)網(wǎng)能增加柑網(wǎng)室的溫度和濕度，同時(shí)降低柑網(wǎng)室的光照強(qiáng)度和光照時(shí)間，冬季對(duì)柑橘害蟲(chóng)的數(shù)量沒(méi)有影響，防蟲(chóng)網(wǎng)導(dǎo)致的柑橘園環(huán)境因子的變化對(duì)柑橘冬稍的生長(zhǎng)沒(méi)有影響。

Abstract： In this study， we mainly studied the influence of insectproof net mulching cultivation technology on the environmental factors of insectproof net and the growth of Citrus. It was found that through the detection of environmental factors， pests and winter tip properties of 40 mesh insectproof net in December. Simultaneously， using the data of changes in environmental factors inside and outside the insectproof net， we conclude that effect of insectproof net on growth of citrus was achieved mainly through common regulation of temperature humidity and illumination intensity in insectproof net.

Key words：insectproof net； citrus； environmental factors； winter tip

冬季，柑橘樹(shù)進(jìn)入相對(duì)的休眠期，生理活動(dòng)相對(duì)較弱，同時(shí)柑橘樹(shù)體經(jīng)過(guò)一年的生長(zhǎng)與結(jié)果，消耗了大量的營(yíng)養(yǎng)物質(zhì)，樹(shù)體衰弱[1]。因此，冬季柑橘園的管理，對(duì)柑橘的生長(zhǎng)具有重要的意義。防蟲(chóng)網(wǎng)覆蓋栽培技術(shù)是柑橘生產(chǎn)體系中防治柑橘病蟲(chóng)害，進(jìn)而提高柑橘樹(shù)生長(zhǎng)的一種有效手段[2]。防蟲(chóng)網(wǎng)覆蓋栽培技術(shù)目前在中國(guó)的生產(chǎn)面積迅速擴(kuò)大。研究顯示，在防蟲(chóng)網(wǎng)栽培環(huán)境下，防蟲(chóng)網(wǎng)的應(yīng)用會(huì)影響網(wǎng)室內(nèi)的小氣候，而環(huán)境氣候是影響柑橘正常生長(zhǎng)的一種重要環(huán)境因子[3]。但是目前對(duì)防蟲(chóng)網(wǎng)對(duì)柑橘網(wǎng)室環(huán)境氣候的研究主要多集中在春夏秋季，對(duì)冬季的研究較少。試驗(yàn)通過(guò)柑桔園防蟲(chóng)網(wǎng)的覆蓋，研究12月份不同時(shí)間點(diǎn)網(wǎng)室內(nèi)溫度、濕度和光照等小氣候以及砂糖橘冬稍生長(zhǎng)的變化，并分析網(wǎng)室小氣候和冬稍生長(zhǎng)之間的關(guān)系。
