Abstract

The invention discloses a green rice planting and fish mixed culture method, and relates to the technical field of rice breeding. The method comprises the procedures of paddy field construction, greenrice planting, fish culture in the paddy field, and rice and fish harvesting. The mixed culture method adopted by the invention not only can prevent disease and insect pests, but also can achieve theeffect that each mu of paddy field produces 200-300 jin of fish and 850-1200 jin of rice; in the paddy field for fish culture, the rice yield is 5-10%; because fish is cultured in the paddy field, bio-organic fertilizer and biological biogas slurry fertilizer are used, herbicide is not used, quick-acting chemical fertilizer and the like are not used, pesticide pollution is effectively controlled,water quality is purified, ecological balance is promoted, and a good agricultural environment is guaranteed.

[0040] Example 1

[0041] A green rice planting and fish polyculture method, comprising the following process steps:

[0042] (1) Rice field construction:

[0043] a) Rotate the exposed rice field with a rotary tiller first, and level the farmland with a laser leveler;

[0044] b) Build a 0.8m-high cofferdam around the paddy field (widening and strengthening), as if the rice is planted in a basin, excavate a ring-shaped fish breeding ditch along the inner side of the paddy field stalk, the ditch is 1.0m wide and deep 1.5m (a step is designed every 30 meters of ditch length to prevent farmers from drowning);

[0045] c) Dig ditches and build culverts in the middle of the paddy fields, dig a "well" or "day"-shaped field ditch, the width of the field ditch is 0.7m, the depth is 0.6m, the length, width and depth of the culvert are 7×7×1.6m, and the circular fish breeding ditch The area of Hetian fish breeding ditch accounts for about 10% of the total area of rice fields;

[0046] d) The paddy field shall be provided with inlet and outlet outlets;

[0047] (2) Green rice cultivation:

[0048] a) Seed preparation and seedling raising, select high-quality, compact plant shape, strong resistance, high-yielding high-quality rice varieties for disinfection, soaking seeds for sowing, or soaking and raising rice seedlings for transplanting;

[0049] b) Apply 800 kg of bio-organic fertilizer (base fertilizer) per mu of paddy field, enough for one application;

[0050] c) Rotary tillage the well-leveled paddy field to make the soil fine and soft (this process is divided into rough tillage, fine tillage and leveling);

[0051] d) Transplant seedlings in good time after filling water to a water depth of 9cm. The density of the seedlings is 16,000 holes/mu; 13 days after transplanting, the time when the seedlings grow the first stem is called the tillering stage. During this period, fertilization and spraying are required. Apply biogas slurry fertilizer once (1% of EM bacteria is added to the biogas slurry fertilizer) and the application rate is 300kg/mu;

[0052] e) Water management during the rice growth period focuses on increasing oxygen and aeration, nourishing and living roots, and enhancing the vitality of the root system; during the greening period, appropriate deep water irrigation is beneficial to greening, and shallow water irrigation is maintained at the booting stage, the initial earing stage, and the full earing stage , the rest of the period is mainly to keep moist;

[0053] f) The rice is exposed to the sun for 1 day every 15 days in July to facilitate the downward growth of the rice root system, so that the rice grows more capillary roots, so that the rice can absorb more nutrients and increase lodging resistance capacity, when the rice is most in need of water and nutrients after a few days of drought, the amount of biogas slurry fertilizer sprayed is 300kg/mu;

[0054] g) Spray biogas slurry fertilizer containing silicon (silicon is a beneficial element) when the rice grows 9 leaves; the application rate is 300-500kg/mu; spray biogas slurry containing zinc when the rice grows 13-14 leaves Liquid fertilizer (zinc can prolong the growth period of rice by 5-6 days, thereby reducing the empty rate of rice from 6-9% to 1-3%), the application rate is 200-300kg/mu;

[0055] h) Harvesting of mature rice;

[0056] (3) Fish farming in rice fields:

[0057] a) 15-20 days before putting fish in the fish-raising ditch in the rice field, the fish-raising ditch must be cleaned and repaired, and then thoroughly disinfected with quicklime 50-60kg/mu to kill predators and pathogenic bacteria.

[0058] b) 15 days after rice seedlings are planted, fish are released, and 20 kg of fry are released per mu, mainly grass carp (grass carp feeding accounts for 40% of the total feeding), and with loach and carp, etc., 50 grams of fry can be released per mu. 120 grass carp, 70 carp weighing 50 grams, and loach fry are stocked as loach fry with a body length of 5 cm, and the stocking density is 1,000 fish/mu.

[0059] c) Before the fish fry go to the field, they can be soaked in salt water with a concentration of 3%-5% for 3-5 minutes to disinfect the fish body. When the fish are stocked, the water should be tested, and the fish fry can only be released after the water test is safe;

[0060] d) Fish farming in paddy fields, put a small amount of duckweed, aquatic plants, green grass or bran and decomposed cow dung in the ditch. During the peak growing season, you can feed some animal feed such as minced snail meat and water earthworms. Feed once every 2 days, and the feeding amount accounts for 3% of the body weight of the fish in the paddy field;

[0061] e) Filtration and anti-escape nets must be installed for fish farming in paddy fields. Filtration and anti-escape facilities such as bamboo pole nets, barbed wire nets, and small-mesh nylon nets must be installed at the inlet and outlet to strictly prevent the entry of predators, especially fish in rice fields. escape with the current;

[0062] f) Daily management Insist on patrolling the fields every morning and evening, inspecting the ridges and checking the fish-blocking grids to prevent water leakage and overflow from escaping fish. In heavy rainy days, drain water in time, remove debris that blocks the grids, and keep the drainage unimpeded; if rat holes are found on the ridges, blocked at any time;

[0063] g) Observe the water color changes in the ditch, fish activities, eating, growth and rice growth;

[0064] (4) Harvesting of rice and fish:

[0065] a) The rice is ripe and ready to be harvested;

[0066] b) Before harvesting rice, water is released to catch fish. When fishing, water should be released at night to catch fish.

[0067] In this embodiment, in the step (1), the paddy field is selected to have a river or a large reservoir, the water quality is good, the water volume is sufficient, and there is no pollution source around, the water retention capacity is strong, and it is not subject to flooding and organized irrigation and cultivation. Paddy fields that are deep and watertight, and whose soil environmental quality meets the standards of the agricultural industry.

[0068] In this embodiment, the area of the paddy field in the step (1) is tens of mu to hundreds of mu.
