无核Peng柑新品系—“塔1”Peng柑

以在博罗杨村华作在柑桔场新近选的“塔１”无核Ｐｅｎｇ突变体与亲本品种为材料，研究了两者形态学特性及果实经济性状表现。结果表明：对照相比，“塔１”Ｐｅｎｇ柑在形态学特性上具有较大差异，其叶片气孔极显著地小于对照。     

温州蜜柑叶片与座果关系初探

通过连续2年的田间调查及人工摘叶试验表明,温州蜜柑叶片与痤果密切相关,老、新叶片的比例在1:1～1.5:1之间,有利于丰产稳产,并通过老、新叶片净光合率的测定和比较,从营养的角度初步讨论了温州蜜柑叶片和座果的关系。     

Yield Estimation Model of Citrus Based on Spectral Data and Agronomic Parameters

With the development of precision agriculture, the research that applies Remote Sensing technology, especially hyperspectral remote sensing, to realize crop management, monitoring and yield estimation, has been concerned. Nowadays, the growth-monitoring and yield-estimating methods in rice, wheat and other annual crops develop rapidly with some achievements having already been put into service. But the yield estimation research on perennial economic crops is few. Taking peren- nial citrus trees as the research object, using ASD spectrometer to collect citrus canopy spectral, this article studied and analyzed the citrus of veget＆tion index and its relationship on yield, synthetically considered the influence of the agriculture pa- rameters on crop yield, and finally constructed the citrus yield estimation model based on the spectral data and agronomic parameters. Through the Significance Test and Samples＇ Test, olutained that the model＇s fitting degree was R=0.631, F= 13.201, P〈0.01 and the error rate of estimating accuracy was controlled in the range 3%-16%, proving that the model has statistical signification and reliability. It concluded that hyperspectral acquired from citrus canopy has substantial potential for citrus yield estimation. This study is an application and exploration of Hyperspectral Remote Sensing technology in the citrus yield estimation.

柑桔黄龙病及其综合防治技术

柑桔黄龙病是柑桔生产上一种毁灭性病害,我国主要发生在沿海和部分内陆省份,包括福建、广东、广西、海南、浙江、江西、云南、贵州、台湾和湖南等地。近年来,柑桔黄龙病在我国许多地方呈现扩散蔓延之势,大量柑桔树枯萎死亡,许多柑桔果园被毁,给柑桔产业造成了很大的损失,有效控制该病危害是柑桔生产中迫切需要解决的问题。     

柑橘蛀干性害虫的发生与防控技术

四川柑橘产区为害柑橘树主干和枝条的蛀干性害虫主要有天牛和吉丁虫两大类。其中天牛类中以星天牛、褐天牛和光盾绿天牛发生普遍和为害严重,吉丁虫类则以柑橘爆皮虫和柑橘溜皮虫发生普遍和为害严重。     

瓯柑高产栽培技术

一、园地选择 因地选择交通方便、水源充足、土层深厚、土质疏松、土壤肥沃、海拔600米以下的平地或坡度在25°以下的南向缓坡地。     

尤溪金柑果实内质成分间相关性探讨

探讨了尤溪金柑果实内质成分含量状况,结果表明:多种成分含量间存在密切的相关,其中可溶性固形物、总糖含量变化的趋势一致(正相关);固酸比、糖酸比与可滴定酸含量存在极为密切的相关(负相关)。表明改善尤溪金柑果实品质,关键在于降低可滴定酸含量。
