"Technical Regulations for Water and Fertilizer Integration of Facility Cultivation of Melon" yog ua raws li qhov thib ob ntawm cov txheej txheem tsim qauv hauv zos ntawm Shaanxi Provincial Market Supervision Administration hauv 2019 "Technical Regulations for Water and Fertilizer Integration of Facility Cultivation of Melon" ( project Tus lej: SDBXM-135-2019), los ntawm Weinan Nws tau koom ua ke tsim los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Ua Liaj Ua Teb Hauv Nroog, Pucheng County Agricultural Technology Promotion Center, thiab Yangling Dongfang Qianpu Manor Agricultural Professional Cooperative.
Kev qhia thiab kev tshawb fawb pab neeg ntawm cov chaw cog qoob loo av-fertilizer-dej tswj hauv Tsev Kawm Ntawv ntawm Kev Pabcuam thiab Ib puag ncig, Northwest A&F University tau koom nrog kev tshawb fawb txog av fertility, fertilization thiab dej thiab chiv kev koom ua ke ntawm cov chaw cog qoob loo rau lub sijhawm ntev. Los ntawm 2016 txog 2018, nws ua ke cov kev xyaum ua haujlwm thiab kev tshawb fawb tseem ceeb hauv lub tebchaws thiab kev tsim kho txoj haujlwm "Western Kev tshawb fawb thiab kev loj hlob ntawm cov thev naus laus zis tseem ceeb rau kev txo qis kev siv tshuaj chiv thiab tshuaj tua kab rau melons thiab cov thev naus laus zis tseem ceeb" tshawb xyuas qhov xwm txheej tam sim no ntawm fertilization thiab irrigation. ntawm melons nyob rau hauv chaw cog qoob loo nyob rau hauv Shaanxi xeev hauv Yanliang District, Pucheng County, thiab Fuping County, lub ntsiab Melon tsim thaj chaw ntawm Shaanxi Xeev. Cov teeb meem ntawm kev fertilization thiab irrigation ntau yog ib qho tseem ceeb nyob rau hauv Tuam Tshoj (daim ntawv luam tawm: Guo Yawen li al., 2020, Phau ntawv Journal of Plant Nutrition and Fertilizers), feem ntau tshwm sim nyob rau hauv hais tias qhov zaus thiab tus nqi ntawm irrigation nyob rau hauv cov xwm txheej ntawm dej thiab chiv kev koom ua ke yog. zoo ib yam li lossis txawm siab dua li cov dej nyab thiab cov kav dej, thiab cov dej txuag dej Cov cuab yeej siv tau tsawg. Qhov piv ntawm cov as-ham ntawm basal daim ntawv thov ntawm cov tshuaj chiv yog siab dhau lawm, thiab qhov kev faib ua feem ntawm cov dej thiab chiv topdressing yog me me. Kev xaiv ntawm chiv yog unscientific. Cov neeg ua liaj ua teb feem ntau cia siab rau kev lag luam tshaj tawm rau kev xaiv chiv, thiab cov khoom noj khoom haus tsis sib npaug.
Raws li cov teeb meem saum toj no, Northwest Agriculture thiab Forestry University, Weinan Agricultural Science Research Institute, Pucheng County Agricultural Technology Promotion Center, thiab Yangling Dongfang Qianpu Manor Agricultural Professional Cooperative tau thov rau Shaanxi Provincial Bureau of Technical Supervision los tsim "Kev Sib Koom Tes Technology ntawm Dej thiab Fertilizer for Facility Cultivation of Melon” Regulations, uas tau pom zoo rau xyoo 2019. Cov qauv hauv zos no yog Raws li txoj kev tshawb fawb ntawm cov khoom noj khoom haus, dej xav tau cov yam ntxwv, thiab cov ntsiab lus ntawm cov av noo noo ntawm melons ntawm ntau theem kev loj hlob, muab kev ua si tag nrho rau qhov zoo ntawm kev sib xyaw dej thiab chiv fertilization thiab irrigation system, thiab tsim qhov sib piv, kom muaj nuj nqis, irrigation. quota, thiab irrigation system ntawm nutrient daim ntawv thov nyob rau hauv txawv kev loj hlob theem ntawm melons. Lub sijhawm, nrog rau kev sib xyaw ua ke ntawm kev tswj hwm kev tswj hwm thev naus laus zis ntawm cov dej thiab chiv xws li kev cog qoob loo thiab kev cog qoob loo hauv qab cov khoom lag luam ntawm cov khoom melon hauv Shaanxi. Cov cuab yeej siv tau nrov thiab siv hauv ntau thaj tsam, thiab tag nrho cov nyiaj nitrogen, phosphorus thiab potassium thov ntawm cov chiv chiv tau raug txo los ntawm 65%, 84% thiab 68% piv nrog cov pa fertilization. Lub backwater chiv dej yog kho nrog ultraviolet sterilization chaw kom zoo inhibit cov kab mob hauv cov nroj tsuag dej lub cev. Pwm loj hlob thiab cov nroj tsuag loj hlob ntau luxuriantly. Piv nrog rau cov qauv zoo sib xws, nws muaj ntau dua nyob rau hauv txoj kab nrog cov xwm txheej tsim khoom tiag tiag hauv Shaanxi, nrog cov ntsiab lus kev ua tiav, qhov ntsuas qhov tseeb tsis meej, thiab kev ua haujlwm yooj yim thiab kev siv.
