Abstract

The invention relates to the field of agricultural liquid mulch and discloses seaweed liquid-state mulch powder with a weeding function and a using method thereof. The seaweed liquid-state mulch powder is composed of, by mass, 20-40 parts of seaweed extract powder, 3-5 parts of polyvinyl alcohol, 3-5 parts of carboxymethylcellulose, 3-5 parts of silk protein powder, 3-5 parts of oxygen producer and 1-2 parts of weeding particle. The using method includes: mixing substances in the seaweed liquid-state mulch powder proportionally; adding the seaweed liquid-state mulch powder into water with mass of 8-12 times, stirring, and obtaining mulch liquid after being stirred well; spraying the mulch liquid onto the surface of soil. After the seaweed liquid-state mulch powder is used, the surface of the soil has good film forming effect, soil structure can be improved, and the seaweed liquid-state mulch powder has excellent effect on water retention, temperature insulation and moisture preservation, is easy to degrade and has functions of weeding and promoting root system growing of crops.

Description

technical field [0001] The invention relates to the field of agricultural liquid mulch, in particular to a seaweed liquid mulch powder with a weeding function and a use method thereof. Background technique [0002] In the process of planting crops, plastic mulch is usually covered on the ground after the crops are planted to keep warm and keep moisture, so that the crops can emerge early, mature early and increase yield. The traditional plastic mulch is more troublesome in transportation, lamination and collection, which affects the efficiency. In addition, plastic mulch is easily blown away by the wind, affecting the growth of crops. Moreover, the plastic mulch is easily broken, and it is difficult to recycle the debris after remaining in the soil, and it is not easy to degrade, causing soil pollution, resulting in soil agglomeration and hardening, and a decline in fertility. [0003] The authorized announcement number is CN103613460B, and the Chinese invention patent wit...
