No need to worry about continuous cropping, bacterial fertilizer double supplementation comes to help

In recent years, with the increase in protected agriculture area and the extension of planting years, combined with the inconvenience of relocating greenhouses and plastic tunnels and rotating crops in open fields, soil-borne diseases of protected crops such as strawberries and tomatoes have become increasingly serious, and these are inseparable from continuous cropping. So, what are the reasons that continuous cropping causes serious consequences?

First, soil-borne diseases worsen year by year. Planting one crop year after year causes the number of pathogens of one or several soil-borne diseases in the soil to increase year by year, often leading to root rot and dead plants, increasing the difficulty of disease control; some undecomposed organic matter contains nematodes, etc., causing nematodes in the soil to accumulate more and more.

Second, nutrient elements are missing or imbalanced. Because crops prefer certain nutrient elements, continuous cropping causes the loss of preferred elements in the soil layer. Moreover, heavy application of phosphorus and potassium fertilizers causes the fixation of certain medium and trace elements, resulting in various deficiency symptoms, reducing plant immunity, facilitating infection by soil-borne diseases, and worsening disease occurrence.

So, what measures should be taken to solve the problem of continuous cropping?

First, supplement beneficial microorganisms in the soil. Beneficial microorganisms have the effects of killing soil-borne pathogens, repairing soil microbial flora, and accelerating the release of phosphorus, potassium, and medium and trace elements fixed by the soil. When applying base fertilizer, it is recommended to apply Likang 10-20 kg/mu or Likang Fudi 20-40 kg/mu as base fertilizer; from the seedling stage to before full flowering, apply Tukangyuan 2-3 times by flushing, 5 liters/mu each time, with an interval of 10-15 days.

Second, improve the soil and increase soil looseness. This can be done by applying Heliyuan or Jiguan bio-organic fertilizer 120-160 kg/mu or Kangdi bio-organic fertilizer 80-120 kg/mu as base fertilizer, and Futaiwei calcium powder Tebeigai or Jiguan calcium powder 40-120 kg/mu, to improve acidified soil, increase soil permeability, and reduce soil salinization.

Finally, supplement medium and trace elements through soil testing and balanced fertilization. Fruit tree areas in the north generally lack elements such as iron, zinc, boron, and calcium. When applying base fertilizer, add Hefeng Iron II, Hefeng granular zinc, Hefeng granular boron, Futaiwei calcium powder, etc., and spray Hefeng Iron II, Hefeng zinc, Hefeng boron, fruit and vegetable calcium fertilizer, etc. on the leaves. Fruit tree areas in the south and protected vegetable areas in the north are prone to deficiency of calcium, magnesium, molybdenum, etc. Calcium and magnesium can be supplemented by base application of Futaiwei calcium powder and Futaiwei Wuhe magnesium, or magnesium, molybdenum, and other elements can be supplemented by foliar spraying of Huide nutrient solution and Hefeng molybdenum.
