Organic biological compound fertilizer is the preferred fertilizer for the production of pollution-free crops, and its improper use does not naturally play an ideal role.
First, the amount of fertilization: biological compound bacteria fertility is mild, and multiple application generally does not cause fat damage, but considering the economic benefits of fertilizer input, the amount should be properly controlled. The basic principle of calculating the dosage is: the price per acre of land and conventional fertilizers (or slightly lower). According to the current application amount of fertilizer per mu of land in the country, the application rate per acre of vegetables can be 50-150 kg; the field crops are 50-120 kg per urn, and the fruit trees can be used according to the age of the trees and the amount of fruit produced. Apply 1-20 kg.
Second, the depth of fertilization. Field crops are generally 5-15 cm, and the depth of fertilization is mainly determined by the following three aspects:
(1) Crop varieties. The shallow roots should be shallower and the deep roots should be deeper. (2) Soil type. The application of soil moisture and poor gas permeability is shallow, and the soil is loose and breathable. (3) Soil moisture level. The water is sufficient, and the dry soil should be applied deeper.
Third, the fertilization method (1) Do not use direct seed dressing, as far as the base fertilizer, try not to contact with the seeds. (2) It can be used as a base fertilizer or as a top dressing. In the low temperature season, the base fertilizer should be early, generally 3-5 days before sowing or transplanting, to keep the soil moist, otherwise the fertilizer effect is not quick-acting fertilizer. (3) For crops with a growth time of more than 2 months, they should be applied in divided doses, once every 30-60 days, and the amount of topdressing per mu should be no less than 20 kg. The last top dressing (increased application rate) should be applied 20 days prior to harvest. (4) It can be applied in various ways such as application, application, and acupoint application, but the effect of concentrated application is better (not in direct contact with seeds). (5) The fruit trees can be uniformly grooved at appropriate positions within the canopy drip line. (6) After fertilization, the soil must be covered, and the depth of soil cover is the depth of fertilization. Water must be watered as soon as possible after fertilization, otherwise the fertilizer effect will not be played in time. (7) A small amount of chemical fertilizer can be applied throughout the growing season. This is also in line with the basic policy of the combination of organic fertilizers and inorganic fertilizers advocated by China. (8) When topdressing, the fertilizer can be directly rooted in water, and the effect is more ideal.
