Embodiment 1

[0038] With Bacillus subtilis, Bacillus licheniformis and Lactobacillus plantarum in liquid culture medium (substrate composition: tryptone 10 weight parts, yeast 5 weight parts, NaCl weight part, adjust pH to be 7.0 after dissolving with 800 weight parts distilled water, add water afterwards To 1000 parts by weight of the culture medium, carry out aerobic fermentation in 121° C. and 101 kPa conditions of high-pressure steam sterilization for 20 minutes). The aerobic fermentation condition is a temperature of 28-32° C. and fermentation for 24-72 hours. After the aerobic fermentation is finished, perform anaerobic fermentation to obtain a composite bacterial culture solution, and the conditions for the anaerobic fermentation are: temperature 28-35°C, time 36-72h. The number of colonies of Bacillus subtilis and Bacillus licheniformis in the composite bacterial culture solution is ≥10 billion cfu / g, and the number of colonies of Lactobacillus plantarum is ≥2 billion cfu / g. After ...

Embodiment 2

[0040] With Bacillus subtilis, Bacillus licheniformis and Lactobacillus plantarum in liquid culture medium (substrate composition: tryptone 10 weight parts, yeast 5 weight parts, NaCl weight part, adjust pH to be 7.0 after dissolving with 800 weight parts distilled water, add water afterwards The culture medium is 1000 parts by weight, and the aerobic fermentation is carried out in a high-pressure steam sterilization under the condition of 121°C and 101kPa for 20min). After the aerobic fermentation is finished, perform anaerobic fermentation to obtain a composite bacterial culture solution, and the conditions for the anaerobic fermentation are: temperature 28-35°C, time 36-72h. The number of colonies of Bacillus subtilis and Bacillus licheniformis in the composite bacterial culture solution is ≥10 billion cfu / g, and the number of colonies of Lactobacillus plantarum is ≥2 billion cfu / g. After the cultivation is completed, add porous starch to the composite bacteria culture solu...

Embodiment 3

[0042] 1) Sowing seedlings

[0043] Seedling raising method: In this embodiment, early rice seedlings were raised in plastic trays, and Zhongyou 402 was selected as an early rice variety.

[0044] Seed treatment: dry the seeds for 1-2 days before sowing, after selecting the seeds in clean water, pre-soak them for 8-12 hours, lift them up to dry, and use prochloraz to soak the seeds for 12-24 hours to disinfect the seeds, then wash and soak the seeds in clean water 8-12 hours, then germinate and sow.

[0045] Sowing time: Generally, when the average daily temperature of early rice reaches 12°C, it can be planted in the sun and covered with film for heat preservation.

[0046] Seeding rate: 1.75-2.0 kg, 45-50 plastic trays with 561 holes for plastic tray seedling cultivation.

[0047] Seedling field management: Choose a field with fertile soil, convenient drainage and irrigation, and light pest damage as the seedling field. Fertilization is mainly organic base fertilizer, with...

Abstract

The invention belongs to the technical field of agricultural ecological breeding, and particularly relates to a rice-duck comprehensive planting and breeding method. The rice-duck comprehensive planting and breeding method comprises the steps that when the leaf age of rice seedlings reaches 3.5-4.0 leaves, the rice seedlings are transplanted into a rice field, a wide-row narrow-plant planting manner is adopted for rice transplanting, and composite viable bacteria microspheres are applied after transplanting is completed; and go-to-field duck breeding is carried out: feed containing the composite viable bacteria microspheres is adopted for supplementary feeding before ducks are put into the field, the ducks are put into the rice field after feeding is completed, excrement of the ducks is discharged into the rice field, and the problems that in the prior art, in a duck-rice co-cropping manner, the prevention and treatment safety of rice blast is poor, and multiple times of pesticide application are needed can be solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural ecological breeding, and in particular relates to a method for comprehensive breeding of rice and ducks. Background technique [0002] Rice-duck co-cultivation means that after the rice is transplanted (tossed) and planted back to green, the ducklings are put into the rice field until the rice is headed and filled with grain. support system. In the rice-duck co-cropping model, ducks have good weeding, insect-killing, and fertilizing effects on rice production, and play a role in cultivating muddy water and stimulating growth. Rice-duck co-cropping can reduce the use of chemical fertilizers and pesticides and produce high-quality organic rice. In the rice-duck co-cropping mode, the duck breeding environment is good, the disease resistance of ducks is enhanced, the survival rate is improved, and the quality of duck meat is improved. [0003] Rice blast is an important disease of rice caused b...
