Problems solved by technology

This invention decomposes macromolecular substances in the soil by using enzyme preparations to coat crop seeds to provide nutrients for crop growth. This product is insufficient: the aftercoat may affect the germination rate of the seeds, and the original aftercoat of the seeds may be destroyed during use. Solid powder The product is not easily subjected to aftercoating

Embodiment 1

[0019] Each component was filtered through a sterilizing plate frame, sucked into an automatic liquid mixing tank according to the weight percentage of Example 1 in Table 1, mixed evenly, filtered through a microfiltration membrane with a pore size of 0.1 μm, and quantitatively filled after passing the test.

[0020] When rice seeds are soaked for the last time of germination, the seeds are soaked for 6 hours with a compound enzyme aqueous solution with a concentration of 0.5%, and then normally sow and raise seedlings.

Embodiment 2

[0022] Each component was filtered through a sterilizing plate frame, inhaled into an automatic liquid mixing tank for compounding according to the weight percentage of Example 2 in Table 1, filtered through a microfiltration membrane with a pore size of 0.3 μm, and quantitatively filled after passing the test.

[0023] When rice seeds are soaked for the last time of germination, the seeds are soaked for 4 hours with a compound enzyme aqueous solution with a concentration of 1%, and then normally sow and raise seedlings.

Embodiment 3

[0025] Each component was filtered through a sterilizing plate frame, sucked into an automatic liquid mixing tank for compounding according to the weight percentage of Example 3 in Table 1, filtered through a microfiltration membrane with a pore size of 0.8 μm, and quantitatively filled after passing the test.

[0026] When soaking the rice seeds for the last time of germination, the seeds are soaked for 3 hours with a 2% compound enzyme aqueous solution, and then normally sow and raise seedlings.

Abstract

The invention discloses an enzyme preparation composition for paddy rice and a use thereof, and belongs to the field of agricultural additives. The enzyme preparation composition for paddy rice comprises 45 to 50% of a peroxidase, 15 to 20% of a neutral protease, 15 to 20% of an amylase and 10 to 25% of cellulose. The enzyme preparation composition for paddy rice has the advantages that use is convenient; a plantation process is avoided; a water loss of seedling roots is avoided in seed germination; a percentage establishment of paddy rice seedlings is greatly improved; and a paddy rice yieldincreasing effect reaches to a significant level.

Description

technical field [0001] The invention discloses an enzyme preparation composition for rice and its application, belonging to the technical field of agricultural additives. Background technique [0002] In the process of crop growth, the fertilizers used are mainly nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer and other chemical fertilizers. Excessive application of chemical fertilizers will cause changes in the composition of the soil, resulting in soil compaction and an increase in harmful components in the soil, and excessive application of chemical fertilizers is also the culprit of ecological problems such as eutrophication of water bodies. With the development of biotechnology, experts from all over the world are working hard to study the method of improving soil with biology, and now a variety of microbial fertilizers have come out. However, the effect of microbial fertilizers is greatly affected by the weather and soil environment, and the storage p...
