Facility vegetables often have abnormal growth in low-light, low-temperature, phytotoxicity and other adverse environments. The affected seedlings can be adjusted with biological nutrient solution to enhance the absorption capacity of soil fertilizer and water.
1. The seedlings are cold-resistant, anti-drug, and haze. Plant growth conditioning small prescription: facility vegetables often have abnormal growth in low-light, low-temperature, phytotoxicity and other adverse environments. The affected seedlings can be adjusted with biological nutrient solution to enhance the absorption capacity of soil fertilizer and water.
2, farmer fertilizer and fat damage remedy small prescription:
(1) Remedial measures for the application of unfertilized farmyard manure to the field: The farmyard manure is not decomposed, and can be evenly mixed according to the ratio of 2 to 3 cubic meters of farmyard manure + 2 kg of rot fungus enzyme. After rotary tillage, water is poured into the greenhouse. The smell can be fixed after three days.
(2) Treatment measures of vegetable seedlings in vegetable seedling stage: When watering for the first time in the seedling stage, use Bacillus subtilis wettable powder with water or root irrigation, the dosage is 1000 g/mu. It can also use 4 kg of rot fungus enzyme per acre to replenish high-quality microorganisms in the soil and reduce the phenomenon of crops falling and killing.
(3) Remedial measures for fat burning seedlings: The bottom seed is not decomposed with farmyard manure to cause burning seedlings, and the rot fungus enzyme can be used to alleviate the fertilizer damage. The dosage is about 0.3 mu per 2 kg of rot fungus enzyme; the rot fungus enzyme can also be used for irrigation. Roots alleviate the damage, use 2 kg of rot fungus to 50 kg of water, and 1000 seedlings.
3, wintering cultivation light prescription: Hebei Province in winter, short nights, cloudy days, rain and snow and cloudy days, low temperature and low light environment is extremely unfavorable for plant growth. In the greenhouse production, fill light and reflective film can be used to increase the illumination and prolong the growth time of the plant. Among them, the fill light is erected every 5 meters, and can be extended for 2 hours in the morning and evening, and a reflective film is placed on the back wall to increase the scattered light. In addition, a carbon dioxide release device can be installed in the shed to enhance photosynthesis and promote crop growth.
4, seed drug coating disease prevention small prescription: with 6.25% sputum nitrile · fine metal creamer 62.5 g / liter 10 ml, 150 ~ 200 ml of water coated 3-4 kg seeds, can effectively prevent vegetable seedlings Diseases such as dryness, anthrax, and tripping occur.
5. Prepare a small prescription for the seedbed soil: mix the large field soil with the decomposed organic fertilizer and the decomposed organic fertilizer at a ratio of 6:4, and add 100g of 68% fine nail cream·manganese-zinc water dispersion powder per cubic meter of seedbed soil. When the agent and 100 ml of 2.5% of the music are used, and after the seed is planted with the soil, the surface of the seedbed is sprayed with the 400% fine nail cream and the manganese zinc water dispersible granule 400 times, which can effectively prevent the vegetable seedlings from drying out, anthrax and tripping. And other diseases occur.
6. Prepare a small prescription for the nutrient matrix of the plug: prepare the substrate according to the ratio of 2:1 of peat: vermiculite, and add 1-1.5 kg of ternary compound fertilizer per cubic meter of matrix (the ratio of ternary compound fertilizer NPK is 15:15: 15, if it is winter and spring seedlings, you need to add 2 kg), while adding 100 grams of 68% fine nail cream · manganese zinc dispersible granules and 100 ml of 2.5% flavonoid suspension seed coating agent for soil sterilization .
7. Fermentation treatment of farmyard manure: Pre-fertilized chicken, cattle, pigs and other farmyard manures are mixed with humic enzymes and crop straws, and 5 kg of ammonium bicarbonate fertilizer (farmers often mentioned) , high temperature rise, fast fermentation. (Every 2~3 cubic meters of farmyard manure + 500 kg of crushed straw + 2 rot of enzymes), covered with discarded plastic film, can be fully fermented in 10 to 15 days.
8. New shed room soil improvement small prescription: use 6-8 cubic meters of farmyard manure plus 6 kg of rot fungus enzyme per acre and mix it evenly into the shed, deepen the soil, enhance soil permeability and activity, and 7 to 10 days later Planting production.
9, high temperature shack sterilization small prescription:
(1) Clean shed: After harvesting the crops from June to July, remove the crop residues, remove the weeds in the field, and transport them out of the shed for deep burial or burning.
(2) Spreading straw: cut the straw of straw, wheat straw, rice straw and other crops into pieces of 3cm-5cm, corncob, waste mushroom, etc., after crushing, according to 1000kg-3000kg/mu The amount of material is evenly spread in the shed.
(3) Spreading organic fertilizer: 3,000 kg-5000 kg/mu of decomposed organic fertilizer such as chicken manure, pig manure and cow dung, evenly spread on straw or mixed with crop straw and spread. At the same time, mix 30kg of ternary compound fertilizer (effective content of NPK 15:15:15) or 15kg of diammonium phosphate. The specific amount can be determined according to the soil fertility, the type of crops and the mode of planting.
(4) Sacrifice fast-acting agent: Apply a quick-burning agent such as rot fungus enzyme, mix 2 kg per acre, deep-turn 25cm-40cm, and prepare the flat for irrigation.
(5) Irrigation: Irrigation of the soil in the shed to full humidification, the relative humidity reaches about 85% (the surface has no clear water, and the soil is not scattered by hand).
10. Precipitating and sturdy small prescriptions: After the vegetable seedlings grow out of the true leaves, they can be treated with strong and disease-resistant biological bacteria. The seedlings are irrigated with humic acid/amino acid foliar fertilizer or 1 billion live spores/gram NCD-2 Bacillus subtilis wettable powder 200 times to promote seedling growth and enhance seedling stress resistance.
11, seedling prevention and control virus spread small prescription: First, the installation shed room installed 50 mesh insect net and hang in the shed indoor yellow trapping board, 30 pieces / acre. The second is to use 35% thiamethoxam suspension agent 2000 ~ 3000 times liquid to spray and root the seedlings, which can effectively prevent and control the pests and aphids of the whitefly, and prevent the spread of diseases such as viral diseases. The efficacy period is 30 More than a day.
12, small control of seedling stem rot disease prevention and control: before the seedling planting with 68% fine nail cream · manganese zinc water dispersible granules 500 times liquid or 6.25% refined A · fluke nitrile 500 times liquid, the soil surface of the planting hole Spraying and then planting the seedlings can effectively prevent stem rot.
