Ukutshala kwe-Asparagus
Ukusabalalisa
Ukusabalalisa kwenziwa ngembewu.
Indlela Yokutshala
Ukuhlwanyela ngokuqondile imbewu yesikhumba se-asparagus kungenziwa kodwa kungcono ukutshala imbewu emanzini futhi emva kwezinyanga eziyishumi kuhlwanyela kuphela izithombo ezinamandla kakhulu. Dweba umdwebo owuhlobo olubanzi lwe-V mayelana no-200 mm endaweni esitshalweni bese uhlwanyela izithombo (noma amakhanda amancane) emgodini bese umboza ngomhlabathi we-50 mm. Uma izithombo sezihlaziye futhi imiqhele yezitshalo zakhiwe futhi, njengoba lesi sitshalo sikhula, simboze ngenye inhlabathi enqunyelwe ukuqinisekisa ukuthi umqhele uhlanganiswe ngamamitha angu-150 emhlabathini.
Indawo evulekile
Izimila kufanele zihlukaniswe ngamasentimitha angama-20 kuya ku-30 emigqeni ephakathi kwamamitha angu-150 kuya ku-200 cm. Lokhu kuphakathi kuka-20 000 no-30 000 izitshalo ngehektare.
Isikhathi sokuhlwanyela
Hlwanyela imbewu ngasekupheleni kwehlobo kuze kube sekwindla ngasekuqaleni kwezinyanga eziyishumi izithombo zakho noma umqhele uzobe usulungele ukutshala.
Isikhathi sokutshala
Ukutshala kwenziwa ekuqaleni kwentwasahlobo kuze kube sehlobo. Kusukela ngo-Agasti kuya ekupheleni kukaNovemba eNingizimu Afrika.
Isikhathi sokukhula
Izitshalo ze-Asparagus zingahlala iminyaka engu-15. Isikhathi sokukhula lapho imikhonto ikhiqizwa futhi ivunwa kusukela ngo-Okthoba kuya ku-Mashi. Ngentwasahlobo ezayo ekwindla zakuqala.
Isivundiso
Ngaphambi kokutshala, ukuhlaziywa kwenhlabathi kufanele kwenziwe ukuze kuqinisekiswe izidingo zomsoco. Uma inhlabathi ingama-asidi amaningi, khona-ke i-lime kufanele isetshenziswe futhi ilinywa enhlabathini okungenani inyanga ngaphambi kokutshala. Ngaphambi nje kokutshala kuqala ukusetshenziswa komquba wezinkukhu noma okungenani 1000 kg we-NPK ingxube 2: 3: 2 kufanele ifakwe enhlabathini engaphezulu kuka-400 mm.
Uma izitshalo seziqedile futhi izibonakaliso zokuqala zomkhonto zibonakala, sebenzisa 800 kg ngehektha ngalinye lika 2: 3: 4. Uma nje imikhonto yokuqala isivunyiwe isicelo esengeziwe se-nitrogen ngesimo esingu-150 kg ngehektare ngalinye le-LAN lingasakazeka emigqeni yezitshalo. Isicelo sokugcina emva kokuvuna sika 150 kg ngehektare ngalinye le-LAN singanikwa amasonto ayisithupha emva kwesikhathi sokuvuna.
Ukunisela
Faka isicelo sama-25 ukuya ku-30 mm wokunisela ngesonto kuze kube yilapho uhlelo lwempande lusungulwa futhi ngemuva kwalokho lezi zinhlelo zingadluliselwa ezinsukwini ezingu-14 phakathi nesikhathi sokuvuna. Uma kwenzeka imvula lezi zinkomo zinganciphisa futhi ngesomiso esibi kakhulu noma emswakama omswakama obushushu, izicelo zinganyuswa. Noma yikuphi indlela qinisekisa ukuthi usebenzise ukuhlolwa kokuswakama kwenhlabathi noma yi-probe ye-neutron, amamitha wezingqinamba noma izindlela zokusebenzisa amandla usebenzisa i-spade noma augur.
