The kiwifruit suffered floods, which led to the widespread death of the kiwifruit planted. Is it possible to reconstruct the original site? Zhu Xinrong, a reader recently, called to ask about this issue. The reporter interviewed the chief expert of the Kiwifruit Experimental Demonstration Station of the Northwest A&F University and Liu Xiande, a scientist of the technical system cultivation of the kiwifruit in Shaanxi Province. The experts stated that the site was blindly built. It was mainly due to reasons. There are three points: First of all, the land where kiwifruit is planted can suffer from flooding, which proves that its plantation is in a low-lying position. Kiwi is a kind of fruit tree that needs water and is afraid of earthworms and weak in moisture resistance. Excessive water in the ground causes poor permeability of the soil, causing the capillary roots of kiwifruit to fail to breathe normally, causing diseases in the roots and causing death. This characteristic requires special attention when selecting the kiwifruit planting area. Secondly, the replanting of the newly planted kiwifruit will result in insufficient survival, poor growth, and poor resistance due to the inability to absorb sufficient nutrients. Third, many plants will emit some toxic substances after their death. Like humans suffering from uremia, such toxic substances will have a very adverse effect on newly planted plants, making it difficult to survive. Liu Zhande suggests that if you want to build a site on site, you have better do it after 3-4 years. Don't blindly.
