Method for producing short-day strawberry flowering seedlings in central region of Yunnan province

The invention discloses a method for producing short-day strawberry flowering seedlings in the central region of Yunnan province. The method comprises the steps of variety selecting, stock plant field planting curing, seedling breeding and short-day flowering processing. The short-day strawberry variety with the properties that the number of flowers in simple inflorescence is more than 20, the flowering time of a single flower in the same inflorescence is scattered, and the flowering time of the simple inflorescence lasts for one or more months is selected; the stock plant field planting curing, the seedling breeding and short-day flowering processing are carried out in the central region of Yunnan province with the altitude ranging from 1,600 meters to 1,900 meters; a nutrient solution including 100-150 milligrams per liter of N, 20-25 milligrams per liter of P and 80-100 milligrams per liter of K is used for watering the seedlings during the stock plant curing period, the seedlings are processed for 10 hours in the short day and processed for 30-35 days under the natural temperature condition, and flower bud differentiation is achieved in more than 90 percent of seedlings. The flowering cost is low, the flowering seedling supply time is early, 30-40 seedlings can be harvested in each stock plant in the middle ten days of June, the fresh autumn short-day strawberries can be produced, and normal winter and spring fresh strawberry production can be guaranteed.

Soil cultivation method for potato virus-free basic seeds

The invention discloses a soil cultivation method for potato virus-free basic seeds. The method comprises: 1) production of a tissue culture seedling; 2) rooting and strengthening; 3) soil cultivation; and 4) harvesting and storage, wherein the step 2) rooting and strengthening comprise: taking out the tissue culture seedling suitable for fixed planting out of a culture bottle; removing root systems and cleaning a culture medium; soaking the roots for 10-15 minutes by using a NAA50 mg/L+2-4 D 5 mg/L rooting agent; then fixedly planting the roots in a soilless culture medium, and keeping the temperature and humidity by using a plastic arch-shaped shed to accelerate the tissue culture seedling to take root, sprout and quickly grow; 12 days after fixed planting, starting spraying a nutritional liquid, spraying the nutritional liquid once at an interval of five days, and spraying the nutritional liquid three times; in 29-32 days after fixed planting, uncovering plastic of the arch-shaped shed, and selecting robust tissue culture seedlings, wherein the height of the seedlings reaches 10 cm and the blades are longer than 1 cm, and transplanting the tissue culture seedlings in pre-treated field soil. By adopting the soil which replaces the medium to culture the potato virus-free basic seeds, the production cost is greatly lowered, so that the market supply price is lowered, and the method plays a positive role in generalizing and popularizing virus-free potatoes.

Contaminated soil biomineralization remediation method based on agricultural waste recycling

The invention discloses a contaminated soil biomineralization remediation method based on agricultural waste recycling, which organically combines agricultural waste recycling, heavy metal contaminated soil organic activation and heavy metal biomineralization remediation, and comprises the following specific steps: carrying out deep degradation and comprehensive utilization on agricultural wastesby adopting a multi-stage biodegradation technology; applying an organic acid solution generated by biological fermentation of the agricultural wastes to heavy metal contaminated soil organic activation; applying residues of biological fermentation of the agricultural wastes to culture of mineralized microorganisms and compost maturation; and using the cultured mineralized microorganisms for treating organic activated soil, and returning compost to the field to supplement soil nutrients. The method is suitable for restoration and treatment of heavy metal contaminated cultivated land soil around mining areas and metallogenic zones, has few equipment and facility requirements, is low in treatment cost, good in restoration effect and easy to master, and is beneficial to improvement of miningarea soil, guarantee of mining area agricultural product safety and promotion of mine land harmony and ecological mine construction.

Myzus persicae and myzus persicae braconid reproduction method of reproduced tobacco plants

The invention discloses a myzus persicae and myzus persicae braconid reproduction method of reproduced tobacco plants. The method includes the steps of when first-time aphid and braconid reproduction is finished or field tobacco leaf harvest is finished, cutting off stems, over 20-25 cm above the ground, of the tobacco plants without diseases and insect pests, loosening and ridging the soil, applying fertilizers, making the tobacco plants grow for the second time, reserving one robust lateral bud in sprouted new buds to continue cultivation, and clearing away the rest of the lateral buds; when each reproduced tobacco plant has 7-9 new leaves, inoculating the lower middle part of each tobacco leaf with aphids, covering an insect proof net after aphid inoculation, and inoculating braconid after aphid reproduction. According to the method, no seedling culture and transplanting are needed, and a greenhouse or other infrastructures do not need to be constructed or occupied, so that the inoculating aphid or inoculating braconid tobacco plants used for flue-cured tobacco braconid reproduction can be directly cultivated to be the reproduced tobacco plants for second-time reproduction of inoculating aphids and inoculating braconids. Meanwhile, according to the method, reproduced tobacco plant braconid reproduction can be directly conducted in the field, the cover net is opened after braconid reproduction, and adult braconids are allowed to spread freely to increase the amount of the braconids in the field and improve the control effect on aphids in the field.
