Biogas is believed to be familiar to everyone, especially those who have planted crops. Biogas fertilizer is recognized as a harmless fertilizer because it kills many harmful germs and eggs during the fermentation process. In these years of agricultural technology, biogas production has also developed at a relatively fast rate. Many vegetable farmers have applied biogas slurry and biogas residue to the production of tomatoes, which has increased the yield of tomatoes and reduced pesticide residues. The standard for pollution-free vegetables. So today, Xiaobian talks about the application technology of biogas fertilizer in tomato cultivation.
1. Tomato soaking can be used for biogas slurry
The biogas slurry contains water-soluble nitrogen, phosphorus, potassium and other trace elements and stimulating substances, which can effectively promote the growth of tomato seedlings, and also has the effect of sterilizing and inhibiting the occurrence of pests and diseases. The specific method is to immerse the tomato seeds for 1-2 days, soak them in the filtered biogas slurry for 8-12 hours, that is, prepare the next seed.
Second, the use of biogas residue for tomato soil improvement
Biogas residue is a solid residue of organic matter fermented to produce biogas. In addition to containing a large amount of available nutrients such as nitrogen, phosphorus and potassium, it is also rich in organic fertilizer and humic acid, which can obviously improve the physical and chemical properties of the soil and fertilize the soil.
Third, using biogas slurry for topdressing to prevent tomato diseases
During the flowering of the tomato, the leaf surface is sprayed with the biogas slurry dilution to evenly wet all the leaves and flower buds. In the flower bud differentiation stage of tomato, foliar fertilizer is used to promote flower bud differentiation, flower buds are more, fruit setting rate is high, and no deformed fruit is produced. Tomato plants do not decay prematurely, can continue to flower, and have a long harvest period and high yield.
The above is the relevant content of the application technology of biogas fertilizer in tomato cultivation. It is believed that many growers may not be aware of the usefulness of biogas fertilizer. You can refer to it, which not only saves fertilizer but also increases the yield of tomato.
