Multifunctional additive for greening seedling growth substrate

Abstract

The invention discloses a green nursery stock planting substrate multifunctional additive, which is characterized in that the additive comprises the following components in weight portion: 1)150 to 200 portions of vegetable carbide; 2) 5 to 10 portions of polyacrylamide type high absorbent resin;3) 0.5 to 1 portion of inorganic fertilizer or compound fertilizer containing nitrogen, phosphorous, kalium elements and the like; 4) 0.05 to 0.1 portion of encapsulated type slow / controlled release fertilizer; 5) 10 to 20 portions of organic fertilizer; and 6) 0.03 to 0.05 portion of compound microbial inoculum comprising photosynthetic bacteria, actinomycete, microzyme, lactobacillus, rhizobium, bacillus and thiobacillus. By the additive, the planting survival rate of nursery stock is more than 98 percent, and the additive also has the advantages of quick seedling recovery, vigorous rooting, vigorous growth and obvious effects.

Description

technical field [0001] The invention relates to an additive for seedling planting substrates, in particular to a fertilizer and a soil conditioner for improving and improving soil quality in greening and afforestation construction. Background technique [0002] With the development of my country's ecological construction, afforestation is becoming more and more important in my country's ecological construction, and people's quality and requirements for greening are getting higher and higher. The planting substrate is the basis of plant growth, and the quality of the substrate is directly related to the growth status of the plants. Such as Chinese patent CN1311287 long-acting multifunctional soil additive and CN1343754 nutritional desert and soil additive. Use water-absorbing clay mineral bentonite and / or zeolite as desert and soil additives, add to desert and soil to absorb water, store water, fix sand, and slowly release the absorbed water and the plant nutrients it carrie...
