Different Foliar Fertilizer Treatments Affect the Yield and Quality of Brassica napus L.for Both Vegetable and Oil Dual-Use Rape

Field experiments were carried out to study the effect of different foliar fertilizer treatments on the agronomic traits,yield,and quality of Brassica napus L.for both vegetable and oil dual-use rape.The seedlings of‘Youtai 929’,‘Jinyoutai 1’,and‘Zhongshuang 11’were sprayed with potassium dihydrogen phosphate,naphthylacetic acid,and selenium fertilizer,and the agronomic traits,yield,and quality were determined.The results showed that the naphthylacetic acid treatment had the highest indexes before winter,followed by the selenium fertilizer treatment.At the harvesting stage,the plant height,number of siliquae,yield per plant,and number of effective branches on the main stem of the three varieties were the highest in the naphthylacetic acid treatment,followed by those in the potassium dihydrogen phosphate treatment.The fresh shoot quality was the best in the selenium fertilizer treatment and the second in the naphthylacetic acid treatment.‘Jinyoutai 1’applied with naphthylacetic acid had the highest economic benefit of 4971.78 CNY/667m2,which was 642.32 CNY/667m2 higher than that of the control.The findings suggested that naphthylacetic acid was suitable to be used as the foliar fertilizer for the seedlings of B.napus varieties for both vegetable and oilseed,and the additional application of selenium fertilizer demonstrated better effect.

Preliminary Research on Biological Characteristics of Scopula subpunctaria in Shandong Tea Region

[Objectives]The paper was to observe the life history and living habits of Scopula subpunctaria in Shandong tea region.[Methods]The occurrence period and duration of each insect state,as well as duration of each instar larvae in various generations were investigated and statistically analyzed.[Results]There were 6 generations of S.subpunctaria per year in Shandong tea region.Different from southern tea region,S.subpunctaria survived the winter as pupae and larvae in tea trees in Shandong,and the duration of overwintering eggs was greatly affected by temperature.The generations of S.subpunctaria overlapped seriously.[Conclusions]The results provide a basis for the comprehensive treatment of S.subpunctaria in Shandong tea region.

Prevalence Characteristics of Rice Black-streaked Dwarf Virus Disease and Continuous Control Strategies

Through summarizing the prevalence characteristics of rice black-streaked dwarf virus disease(RBSDVD)in Linyi City of Shandong Province,this paper analyzed its prevalence is related to changes in farming and cultivation systems,the increase in the population of venomous Laodelphax striatellus Fallén and its own migration and spread,the poor disease resistance of cultivated varieties,and inadequate time of prevention and control.Besides,based on the practice of local control,it came up with some comprehensive control measures including strengthening monitoring,early warning and forecasting,planting resistant(tolerant)rice varieties according to local conditions,appropriately delaying the sowing(planting)period,supplemented by insect nets to cover seedlings,and making scientific use of chemical control.It is expected to provide a reference for the prevention and control of RBSDVD.

Identification of Mulberry Endophytic Fungus Macrophomina phaseolina Strain

An endophytic fungus MOD-1 was isolated from the roots of mulberry trees,and was identified as Macrophomina phaseolina by morphology and molecular biology.The 5.8 S rDNA/ITS region sequence of the strain has been registered in GeneBank with the accession number of EU250575.

Design and field test of a special Chinese herbal medicine harvester

A special Chinese herbal medicine(SCHM)harvester was designed to address the problems such as the highly labor-intensive process,low harvesting efficiency,and lack of suitable machinery.The designed machine was comprised of three main components,including a reciprocating cutter,a clamping chain,and a counter roller.In addition,a mechanical model of a plant stalk during harvester operation is established to analyze the parameters affecting SCHM harvesting:sprocket rotation speed,counter roller gap,and header inclination angle.Considering the operating mode of the harvester,all three parameters were taken as test factors,and the proportion of lost fruit,the proportion of broken capsules,and the length of the retained stem are the test indicators.According to the test results,the fruit lost was 1.14%,the broken fruit was 1.02%,the stalks with an acceptable length was 82.45%at a sprocket rotation speed of 110 r/min,a roller gap of 9 mm,and a header inclination angle of 5°.The research can provide an effective solution to solve the SCHM harvest problem.Further studies need to do for making this machine more automated and intelligent.
