Embodiment 1

[0022] After paddy rice (Huaidao No. 5) is planted and finished, select the nylon net of 40 orders, width 75cm for use.

[0023] Lay nylon net on the field surface inside the ring ditch, cover with the soil of excavating the ring ditch, covering thickness 5cm, the net width 20cm covered by the soil, and the remaining 55cm nylon net stands up along the rice plants as a seine.

[0024] The erected nylon net is fixed and supported by a bamboo pole every 4 meters, and is surrounded by a circle along the inner side of the ring ditch outside the rice plants, and no additional mud-like auxiliary ridges are made.

[0025] After the nylon net is enclosed, it can be recovered at any time after the rice seedlings are established and before harvesting, and can be reused in the coming year.

[0026] Nylon nets are used as seines to prevent lobsters from entering the rice planting area to clamp on the seedlings during the rice planting period, improve the survival rate of the seedlings, and...

Abstract

The invention provides an auxiliary ridge replacing purse net method suitable for crayfish intercropping in a rice field and belongs to the technical field of crayfish farming and rice cultivation ina rice field environment. The method comprises the steps that before rice planting, a net is laid on the inner-side field surface of a circular ditch of a rice field and is covered by soil, the widthof the net covered by the soil is 18-22 cm, the width of the rest net is erected along rice plants to serve as a purse net, and the operation is omitted that soil is used as an auxiliary ridge. By adopting the method, crayfishes cannot enter a rice planting area in a rice planting period, so that the crayfishes are prevented from damaging rice seedlings, the survival rate of the rice seedlings isimproved, and the effect of stabilizing the number of ears is achieved.

Description

technical field [0001] The invention belongs to the technical field of crayfish cultivation and rice cultivation in a paddy field environment, and in particular relates to a method for using a seine net as an auxiliary ridge suitable for intercropping crayfish in a paddy field. Background technique [0002] With the decline in the benefits of simple grain growing, intercropping of crayfish in paddy fields has become an effective way for farmers to improve land utilization and increase planting benefits. In Yandu District, there are 30,000 mu of crayfish raised in paddy fields, which has become an important local industry that responds to the structural reform of the agricultural supply side. Crayfish nesting in paddy fields excavates ring ditches around the field. The mouth width of the ring ditch generally does not exceed 2.0 meters, the bottom width does not exceed 1.0 meters, and the ditch depth does not exceed 1.5 meters. For high field ridges, the width of the bottom o...
