Background

Earthworms are the main animal group in soil, called as "ecosystem engineers", and can affect soil structure and function through a series of vital activities such as defecation, digging, stirring, etc. Darwinian has pointed out that "a plow is one of the first best inventions for mankind, but the soil has been tilled by earthworms and will also be tilled by it well before the survival of mankind. Modern research also proves that earthworms have a great effect on the formation of soil structures (pores and aggregates). The earthworms can eat soil which is 5-30 times of the dead weight every day, leave a large amount of earthworm casts to be accumulated on the soil surface or the soil in the soil, and the earthworm casts have good cluster structures, so that the volume weight of the soil can be obviously reduced, and the water retention capacity of the soil can be enhanced.

In this process, people cannot control the moving direction and range of earthworms, so that it is difficult to realize the intensive plowing and composting of a specific area (such as an rhizosphere range) according to the requirement of agricultural production. In addition, the earthworm is willing to move in a humid area with rich organic matters due to the characteristic that the earthworm tends to fertilize and tends to water, if the soil fertility and the humidity of the same crop are different, the biological activity range of the earthworm is limited, the plowing and composting differences of the same soil of the same crop are gradually increased, and the comprehensiveness and the directionality of soil composting are not easy to occur.

Therefore, a directional attraction type soil composting method is provided, which utilizes the directional attraction of earthworms to carry out directional composting in the soil moving process.

Example 1:

referring to fig. 1-2, a method for directional attraction type soil composting includes the following steps:

s1, selecting earthworms with strong vitality, selecting one or two of onyx earthworms and red earthworms, and placing the earthworms in a feeding box for feeding for 3-4 weeks;

s2, preparing a directional lure fork capable of being inserted into the soil, placing a plurality of food lure balls 3 on the directional lure fork in a hanging manner, and burying the directional lure fork distributed with the food lure balls 3 in the soil;

s3, placing earthworms on soil to be composted, enabling the earthworms to penetrate into the soil, moving to the directional luring fork under the action of the food luring ball 3, and completing soil plowing and composting in the moving and feeding process;

s4, after earthworms are placed, uniformly spraying the earthworms into the soil, so that each area of the soil is in a wet state;

s5, at last, the directional luring fork is replaced regularly, and a new food luring ball 3 is arranged on the directional luring fork.

Wherein the onyx earthworms and the red earthworms in the S1 have the body length of 18-25 cm and the body thickness of 0.4-0.6 cm, and have good soil turning and composting effects, directional induction forks are intensively buried in soil with the range of 20-30cm of crop root systems every 5-7cm in S2, the directional induction forks are distributed and buried every 15-20cm in other areas, so that the important turning and composting in the range of crop roots are realized, 3-5 earthworms are placed in the soil with the range of 20-30cm of crop root systems in S2, 2-3 earthworms are placed in the soil with the range of 15-20cm in other areas, when a new directional induction fork is replaced in S5, 2-3 earthworms are placed in the soil with the range of 20-30cm of crop root systems, and 1-2 earthworms are placed in the other areas every 15-20cm, the directional luring fork can be replaced, when a new directional luring fork loaded with the food luring balls 3 is buried in the soil, new earthworms are placed properly, the problem that the quantity of the earthworms is reduced due to the soil environment is effectively solved, and in addition, attention needs to be paid to the fact that the burying position can be properly changed within the specification range when the new directional luring fork is buried, so that the distribution uniformity of the earthworms in the soil is effectively improved.

Referring to fig. 2-3, the directional luring fork comprises an embedded rod 1 with a buried tip part arranged at the bottom, a plurality of arc luring rods 2 are distributed on the outer side wall of the embedded rod 1 at the upper end of the buried tip part, cavities communicated with the inside of the embedded rod 1 are formed inside the arc luring rods 2, a plurality of embedding cavities 201 for sleeving food luring balls 3 are formed in the arc luring rods 2 at equal intervals, the embedded rod 1 arranged at the buried tip part is convenient for the directional luring fork to be stably inserted in soil, the arc luring rods 2 are circumferentially distributed, the food luring balls 3 are embedded in the arc luring rods 2, the food luring balls 3 are effectively and uniformly distributed in the soil, and accordingly earthworms can be lured to move as much as possible in the range.
