1. Ntev drought watering
Yog hais tias cov av qhuav heev nyob rau hauv lub sij hawm thaum ntxov, thiab tus nqi ntawm cov dej yog dheev loj heev nyob rau hauv lub tom ntej theem, lub transpiration ntawm cov qoob loo nplooj yuav loj heev inhibited, thiab nplooj yuav yob rov qab thaum lawv qhia lub xeev ntawm tus kheej- tiv thaiv, thiab nplooj yuav dov.
2. Cov nyhuv ntawm qhov kub thiab txias tsis muaj kev puas tsuaj
Thaum qhov kub tsis tu ncua qis dua 10 ° C, mesophyll hlwb ntawm cov qoob loo yuav raug kev txom nyem los ntawm qhov txias txias, thiab nplooj yuav pib wilt. Thaum lub caij nplooj ntoos hlav txias, nws tseem yuav ua rau cov nplooj tshiab tuaj yeem curl!
3. Kev siv cov tshuaj hormones tsis raug
Thaum cov concentration ntawm naphthalene acetic acid siab dhau lawm, cov nplooj yuav qhia qhov tshwm sim ntawm dov rov qab tom qab txau. Thaum 2,4-D yog dipped nyob rau hauv lub paj, lub concentration yog loj heev los yog sprinkled on nplooj, ua rau nplooj tuab, shrinking los yog curling downwards.
4. Kab tsuag puas
Cov mites daj yog me me uas lawv feem ntau nyuaj los txheeb xyuas qhov muag liab qab. Cov tsos mob tseem ceeb ntawm cov nroj tsuag puas los ntawm mites yog nqaim, tawv thiab upright nplooj, shrinking downwards los yog twisting deformities, thiab thaum kawg bald tswv yim. Cov nplooj yuav ua me me, nyuaj thiab tuab, thiab qhov tseem ceeb tshaj plaws yog oily stain nyob rau sab nraub qaum ntawm nplooj, nrog cov tshuaj yej xeb xim. Aphid puas tuaj yeem ua rau cov nplooj curling loj heev, vim tias aphids feem ntau pub rau sab nraum qab ntawm nplooj thiab cov ntaub so ntswg, yog li aphid puas tuaj yeem ua rau cov nplooj curling sib txawv.
5. Nematode puas tsuaj
Kev kis kab mob ntawm nematodes tuaj yeem ua rau cov hauv paus hniav tsis nqus cov as-ham thiab xa mus rau lawv, ua rau mob loj heev ntawm cov hauv paus hniav, ua rau cov nplooj tig downwards.
