How to identify from appearance, the following methods are available for reference:
(1) Phoxim: colorless, slightly pungent medicinal liquid;
(2) Enemy kill: light yellow or brown liquid with slight smell;
(3) Copper sulphate: Lanthanum-colored, odorless;
(4) Carbendazim: white or off-white powdery, slightly odor;
(5) Mayamsone: white powder with a pepper-like odor;
(6) Diocesan: red solid powder foam;
(7) Topotecan: yellow powder, slightly peppery smell;
(8) Kill grass Dan: light yellow, odor liquid;
(9) Trifluralin: red liquid, yellow after watering;
(10) Benzonsone: pale yellow liquid with a pepper-like odor;
(11) Butachlor: light blue liquid with aroma;
(12) Dimethoate: light yellow, with a rancid odor solution.
The meaning of the letters on the pesticide label (1) pH: indicates the pH, when the PH value is equal to 7 is neutral, more than 7 is alkaline, the larger the number, the stronger the alkalinity. Less than 7 is acidic, the smaller the number, the stronger the acidity;
(2) PPm: millions of concentrations. That is, 1 million pharmaceutical liquids, pesticides containing pesticides;
(3) PC: Percent concentration:
(4) Ai: the active ingredient of pesticide;
(5) RD: animal lethal dose;
(6) RD50: the dose that causes 50% of death;
(7) ED: lethal dose;
(8) B: Baume degree, based on the Baume agent to determine the dissolution rate of the liquid. Generally less used, can be found in the Baume degree table;
(9) MAC: maximum allowable concentration;
(10) Wt: weight;
(11) SG: specific gravity;
(12) SP: water-soluble powders;
(13) EC: Emulsifiable concentrates;
(14) C: granules: such as 5% C(g) or 5% granules.
Is there a big difference between a cloudy day and a sunny day when the tomatoes are covered with flowers?
Why does the flower stained with 2.4-D at the same concentration contain deformed fruit? Because in the dip in the flowers, cloudy and sunny days, the effect of dipping flowers is good. Cloudy flowering is relatively speaking, the general sunny day with a good effect. In contrast, the temperature is relatively low on cloudy days. If the same concentration is used for flowering, the phenomenon of dryness, falling flowers and malformed fruit growth will also occur. The main reason is that the concentration is not suitable, and the concentration should be reduced according to the increase of the ambient temperature.
The tomato in the greenhouse is covered with 2.4-D, usually the concentration of the first flower is 20 mg/kg. The second order flower was 15 mg/kg, and the third order flower was 10 mg kg.
The method of flowering is also very important. Generally, most flowers are planted. When there are 3-4 words in the same inflorescence, they can be opened once. Each flower can be stained with auxin and it will become distorted. In the use of auxin can be added a little red advertising color, flowers have been spent on the flowers have been marked, stained time should be from 9:30 am to 10:30 is good.
There is a great relationship between the germination rate of vegetables and the storage period for the effective preservation period of vegetables, and the storage period is different for different types of vegetables.
(1) Tomato: generally can be stored for 3-4 years, the longest is not more than 4 years, otherwise it will reduce the bud rate, the method of identifying the new and old seeds, there is a new hair on the seeds, and there is tomato flavor, the old skin hair less hair or Fall off.
(2) Cucumber: It can be stored for a maximum of 2-3 years. When it exceeds this period, the bud rate is generally reduced by 20-30%. Even if it can emerge, some often have no true leaves after emergence and are not easy to survive.
(3) Eggplant: Seeds with a shelf life of generally less than 6 years can be used. New seeds are shiny and old seeds are reduced in gloss according to their shelf life.
(4) Pepper: Not more than 3 years, otherwise the bud rate will be reduced, the bud rate will be reduced by about 10% for 2 years, 30% for 3 years, new seeds will be golden yellow, and the yellow seeds will be apricot.
(5) Onion Seeds: Vaccinated onions grown in the summer must be seeded with new seeds. If the seeds are aged, the onion will pick up the mossy seeds. Spring onions can use the seeds produced in the first year.
(6) Parsley: It must be stored for one year before it can be used, but it should not be stored for more than three years. Otherwise the scent becomes smaller.
(7) Celery: It can be stored for 3 years. The seeds of the end of the year cannot be used and must be stored for one year.
(8) Amaranth: In the new year, if the new seeds are good, the germination rate will be greatly reduced if stored for two years.
(9) Cabbage: It can be stored for two years. The seeds that were harvested in that year can be planted in the same year. However, if it is more than two years, the emergence rate is reduced by 20-30% and the disease resistance is low.
