Tus kab mob tiv thaiv kab mob
Nqes tes ua haujlwm tsis muaj kev tiv thaiv. Kev tiv thaiv ntawm tus kab mob yog cov cultivation ntawm resistant mus rau kab mob hybrids. Piv txwv, Ghazal F1, Atherosclerosis F1.
Nyeg thinning
On kev xeem, koj pom cov tuag seedlings. Saib cov nroj tsuag hauv ntau yam. Yog hais tias koj pom soj ciav thinning nyob rau hauv daim ntawv ntawm qia stumps, qhov no yog ib tug fungal tau tus kab mob - dib paus rottshwm sim los ntawm feem ntau los ntawm kev ua txhaum ntawm tej yam kev mob loj hlob feem ntau dej siab rau seedlings.
