      大棚番茄反復死棵為哪般?

      時間: 2019-07-17      來源:     



      近來有菜農反映,種植的大棚番茄近年來死棵問題頻發,雖然在夏季歇茬期也進行了高溫悶棚、定植后也及時采取了藥劑灌根等預防措施,但是第二年仍會出現死棵。這是咋回事呢?

      通過了解得知,該菜農偏施化學肥料,忽視有機肥的施用,棚室土壤出現了板結和鹽漬化現象。在這樣的土壤里種番茄,一旦澆水頻繁,就會出現傷根、漚根現象,即使使用再多的藥劑,不對惡化土壤進行改良,番茄死棵就得不到根本解決,仍然會“反復發作”。對此提出如下緩解措施:

      1.增施有機肥。下茬番茄定植前,要增施優質的有機肥,如每畝施用2000公斤以上發酵腐熟糞肥。也可以施用商品有機肥,根據土壤肥力的不同,每畝地施用200~400公斤,提高土壤有機質含量,加速有機質的分解和轉化。

      2.化學肥料適量施用。土壤鹽漬化的出現,一方面是過量施用化學肥料,另一方面是化學肥料的利用率低,大量的養分殘留在土壤中造成的。因此,可通過使用化學的疏松劑或大量稻殼糞等,也能夠改善土壤的通氣狀況,但更重要的是化學肥料適量施用,此外,中微量元素也要注意在底肥中給予補充。

      3.增加微生物菌劑、甲殼素用量。在土壤改良中,有機肥的分解和轉化離不開有益微生物的輔助,因此通過增施有機肥的方式改良土壤,必須增施有益菌。除了具有改良土壤的作用,有益菌還能夠起到以菌抑菌、促生根系等作用。同時,土壤處理或藥劑灌根后也一定要注意補充微生物菌劑,讓有益菌始終占優勢。增施含甲殼素的產品除了能夠很好地促生根系,保護根系外,也具有良好的促生有益菌,抑制有害菌的作用。? 南和縣農業農村局 李杰
