Embodiment 1
[0029] A kind of method for planting weed in the field of co-production of rice and shrimp, the steps are:
[0030] A. Shrimp ditch finishing: Smilax has no strict requirements on the climate and environment, but it must reach a certain water depth of 50cm-200cm to improve water quality. Therefore, the shrimp ditch should be tidied up before the stone buds are planted in September every year, and weeds and sundries in the planting ditch should be removed. If the substrate is hard, tools such as nail rakes can be used to loosen the substrate. Seedbeds should be clarified for 1-2 days before sowing. Before sowing, the water depth in the ditch should be controlled at about 50cm, and the transparency is high.
[0031] B. Provenance collection and preservation: From late May to early June every year, the mature stone buds of Smilax are collected as the provenance. The stone buds are required to be thick, the scale leaves are thick, yellow-brown, and the texture is hard. After the...
Embodiment 2
[0047] According to the basic steps of embodiment 1, as described in the present embodiment, the planting of various aquatic plants such as Smilax verticillum and Hydra verticillium, hornwort together, the technique is as follows:
[0048] The importance of aquatic plants to raising crayfish is becoming more and more obvious, and even become the decisive reason for the success or failure of raising crayfish. Therefore, there are sayings that "the number of shrimp depends on the aquatic plants" and "the grass is the first to raise shrimp". This is not a random talk. It is practiced by the majority of breeding friends for many years.
[0049] A kind of method for planting weed in the field of co-production of rice and shrimp, the steps are:
[0050] 1. Variety selection and matching. The species of aquatic plants planted in the pond mainly include scorpion grass, hydrilla, etc. The transplanted aquatic plants are mainly submerged species, supplemented by floating species, thus ...
Embodiment 3
[0057] Embodiment 3: (application embodiment 1)
[0058] In 2015, a high-yield test of cultivating crayfish seedlings in paddy fields in Zhaonao Village, Qianjiang City, Hubei Province, a total of 40 mu of rice fields were cultivated with shrimp and rice, mainly for raising shrimp seedlings. As of May 12 of that year, a total of 5,600kg of crayfish seedlings were harvested, with an average yield of 140kg per mu, 1,600kg of adult shrimp, with an average yield of 40kg per mu, and a sales income of 257,600 yuan. After deducting land lease fees, staff wages, fertilizers and feed, fish medicine, water and electricity fees, etc., the single net profit of crayfish is 177,600 yuan, and the average profit per mu is 4,400 yuan. In 2016, Mr. Wang did more meticulous work in planting grass, fertilizing and feeding in rice fields. At the beginning of February, when the water temperature was above 101°C, the water plants were fed. The species of aquatic plants in the ditches continued to c...
