In the high-temperature period, the live growth of vegetables is not good, and pests and diseases are also susceptible to nursery cultivation. The vegetables in summer and autumn are mainly cauliflower, cabbage, summer cabbage, lettuce and late autumn pepper, eggplant, and tomato. Summer and autumn vegetable seedlings must be "six defenses", that is, to prevent light, rain, drought, high temperature, pests, and roots.
Determination of the sowing date
The seeding period of the vegetable nursery in the high temperature period should be based on comprehensive consideration of planting patterns, climate characteristics, types of vegetables, and varieties selected. Due to the high temperature, seedling growth and development is fast, and the period of raising the seedlings is significantly shorter than that of autumn and winter vegetables. The melon vegetables only need about 20 days, the eggplant vegetables are about 30 days, and the cabbage vegetables have a seedling age of about 25 days. Nursery facilities
In addition to seedbeds, high temperature vegetable seedlings must use shade and rain protection facilities, use greenhouses, sheds or small arches, covered with shade nets, insect nets, and waste greenhouse films, which can effectively reduce the adverse effects of high temperature and heavy rain on vegetable seedlings. influences. Plot selection
The nursery should be dry and flat, with good soil permeability and water retention, and capable of irrigation and drainage. Avoid breeding seedlings on plots that have been planted with the same vegetable crops on the continuous cropping plot or in order to avoid soil-borne disease hazards and avoid land plots for serious soil pests.
Select fertile garden soil and fully cooked high-quality manure that have not been planted for the same family of crops for many years as bed soil raw materials, and prepare them in a ratio of 2:1 for soil and fertilizer. Each cubic meter of bed soil plus 90% trichlorfon crystals 60 grams, 75% thiram 80g wettable powder, soil, fertilizer, drugs, after mixing well sieved spare. In order to prevent transplant rooting, nutritional seedlings can be used. Seed processing
Warm soup soaking. For example, seeds of melons and solanaceous vegetables are put into warm water of 50-55°C, mixed with hot seeds until the water temperature drops to 30°C, soaked for 6-8 hours, and soaked for 20 minutes with 50% carbendazim wettable powder 500 times. Wash with clean water, and then germinate at 30°C.
Liquor soaking. Seed, liquor and water are weighed in a ratio of 1:0.5:0.5, and the liquor and water are firstly mixed. The seeds are then soaked for 10 minutes. Remove and wash with water.
Potassium permanganate solution soaking. The seeds were first soaked in hot water at 50°C for 25 minutes and then soaked in a 1% potassium permanganate solution for 15 minutes. Soak copper seed solution. The seeds were soaked with fresh water for 10-12 minutes, then soaked in 1% copper sulfate solution for 5 minutes, and then washed with water to prevent bacterial diseases. Carbendazim soaking. After immersing in cold water for 3-4 hours, dip in a 500% solution of 50% carbendazim wettable powder for 1 hour and rinse with water to kill or purify the pepper virus.
Chemical seed dressing. The seeds were placed in a clean container, and 0.3% of the seed weight was added to thiram, carbendazim and other agents, so that the agent adhered evenly to the surface of the seeds and kill a variety of germs.
Do a good job of "six defenses"
Use greenhouses, sheds or small sheds to cover shade nets or waste sheds (mudables) to protect against high temperatures, light, and rain. No old shed film on the seedbed should be covered with a shed film before rain.
Before planting enough water, sow 2-3 times before sowing. After sowing, covered with grasshoppers to keep the seedbed moist, water shortage at seedling stage can be poured in the morning and evening water, add water, prevent heat, drought-induced viral diseases. Insect nets are used to prevent pests such as aphids, whitefly, and spotted fly.
Promote the use of nutrients or paper cups to raise seedlings, reduce the damage to the seedling root system during transplanting, and reduce the occurrence of soil-borne diseases caused by the damage of the root system.

Metatron Hunter 4025:
Description and Field of Application
Purpose
The Metapathia-GR Hunter software can operate only with the telemetric nonlinear analysis data processing apparatus "Metatron" and its subsequent modifications. The telemetric nonlinear analysis data processing device is compatible with the IBM-type PCs and intended for studying reaction of a biological object to different types of the informational impact. "Metatron" allows correlating the measurement process with the process affecting it and performs the following.
Operations:
1) It measures J (0) which mirrors the change of the describing parameter, and the entropic potential relative to its ini- tial value;
2) It transforms continuous signal J (0) with the preset intervals of frequencies into a histogram (a row of numerical val-ues of scanned frequencies with serial numbers from 1.8 to 8.2 Hz.);
3) It sends the current W values to PC and displays the graph on the monitor simultaneously with its impact on the examinee.
4) It accumulates the W value in its memory unit, if observing the histogram is more convenient upon completion of the measurements;
5) It issues the scale-correlated commands required for regulating the effect on the examinee at testing;
6) It transmits the W values from the unit into PC memory upon completion of the measurements and saves them in unit memory of prior to the beginning of recording data of the next measurements.
Telemetric nonlinear analysis data processing apparatus "Metatron" (hereinafter "apparatus") can be used for non-linear analysis of biological structures and testing of biologically active supplements. The apparatus can also be used in research centers and scientific research facilities.
The apparatus is intended to register psychophysics changes in system and allows to:
- Get qualitative estimation of functional condition in a form of topical analysis.
- Control effectiveness and results of different ways of treatment.
- Analyze dynamics of functional condition changes over period of time.
- Determine initial nidus of functional breach.
- Estimate character of changes using expert systems.
- Estimate basic characteristics of bio-system homeostasis.
