                                                                                                                                                                                                                      2018-11-01

                                                                                                                                                                                                                      近兩年,各種作物的爛根死棵現象時有發生,給廣大種植戶造成了不小的損失。引起作物爛根死棵的原因很復雜,只有追根溯源找出病因才能對癥下藥。那么果樹為什么爛根?怎么樣使果樹快速生根?

                                                                                                                                                                                                                      作物為什么爛根

                                                                                                                                                                                                                      1、土壤鹽漬化。隨著種植年限的延長,過量的使用化學肥料,會導致土壤鹽堿化。

                                                                                                                                                                                                                      2、農藥使用導致土壤酸化。包括除草劑的殘留以及以前使用高毒農藥導致的土壤酸化板結、重金屬超標,使土壤保持水分、養分的能力變差,影響作物根系生長。

                                                                                                                                                                                                                      3、根部病害。根部病害主要是根腐病、莖基腐病、枯萎病等,根部病害輕微時必然引起根系受傷,營養吸收受阻,嚴重時就會發生死棵現象。

                                                                                                                                                                                                                      4、線蟲危害。由于根結線蟲為害導致根部形成瘤狀,而導致死棵。

                                                                                                                                                                                                                      5、惡劣的自然條件。春季低溫以及作物移栽后土壤溫度不夠,或者溫度過高;冰雹、暴雨等惡劣天氣。也包括栽培管理過程中的一些不當操作,傷根導致死苗。

                                                                                                                                                                                                                      怎么樣使作物快速生根?

                                                                                                                                                                                                                      作物爛根當然是根系出了問題,在學會預防的同時,我們還要學會使作物快速生根,這樣預防+治療,才能防治爛根問題。
