Greenhouse vegetables are the most popular choice for growers. They are characterized by high yields and are not subject to seasonal restrictions. However, if they are not properly managed, they will suffer from “four evilsâ€, affecting the quality and yield of vegetables. You can refer to the prevention and treatment measures for phytotoxicity, drought, and flail.
First, fat damage
In fact, it is the hazard of salt accumulation, mainly due to partial application of chemical fertilizer or excessive fertilization. Problems arising after the occurrence of fertilizer:
First, it inhibits the development of vegetable roots and weakens the function of water and fertilizer absorption;
Second, the concentration of the soil solution is too large, and the vegetable plant body undergoes reverse osmosis, resulting in physiological wilting or leaf edge dryness;
The third is the toxic gas hazard; the fourth is the vegetable deficiency syndrome.
Second, phytotoxicity
The "four evils" of greenhouse vegetables! Fat damage, phytotoxicity, drought, and flail
There are obvious phytotoxics and the symptoms are obvious. There are hidden phytotoxics, the symptoms are latent or delayed to the squat vegetables. Reasons for phytotoxicity:
First, the selection of pesticides is not correct or misuse of herbicides;
Second, the concentration of the application is too large;
The third is the purchase of inferior pesticides;
Fourth, there is no way to avoid the application of high temperature. After the phytotoxicity, some vegetables quickly lose their green leaves; some produce focal spots and perforations; some fall, fall, fall, or deform; the most serious whole plants wither.
Third, drought
It is one of the most critical factors restricting the development of greenhouse vegetables.
cause:
First, improper selection of vegetable greenhouses, lack of local water sources;
Second, although there is water, the water quality is poor;
Third, the amount of water is sufficient, but the ditch, canal, and irrigation facilities are not matched. Drought damage not only affects the timely sowing of vegetables, but also affects the normal growth of vegetables. At the same time, it brings great difficulties to the management of fertilization and drugs. The effects of drought damage sometimes exceed fertilizer and phytotoxicity.
Fourth, the shackles
In the same greenhouse, the same category or the same vegetable is grown year or quarter.
(1) Reasons for obstacles
First, the same kind or the same kind of vegetables prefer a certain nutrient element, such as deficiency is prone to deficiency syndrome;
Second, the accumulation of soil pathogenic bacteria causes disease to cause dead seedlings;
Third, the secretion of substances in the roots of the same vegetable can easily lead to the loss of balance of soil microbial community structure, resulting in soil aging.
(2) Countermeasures
1. Choose a shed site and improve the water system.
Before determining the greenhouse, it is necessary to check whether the shed site has sufficient water source. If there is sufficient water source, it is necessary to open a ditch and a channel to facilitate water diversion and drainage. Where conditions permit, a water supply faucet should be installed in each shed. Sprinkler irrigation facilities should also be provided for the standard height.
2, to balance fertilization, promote the steady growth of vegetables
First, it is necessary to apply fully decomposed organic farmyard manure all year round;
The second is to apply refined organic fertilizer, high-energy organic fertilizer, such as Ye Meifeng, Guo Meifeng, etc.;
The third is to change the application of nitrogen and phosphorus to reduce nitrogen, stabilize phosphorus, increase potassium, and apply micro-fertilizer;
The fourth is to apply appropriate amount of fertilizer;
The fifth is the occurrence of fat damage in one day, to spray a variety of active liquid fertilizer to alleviate the hazard.
3, scientific use of medicine to ensure the safety of vegetables
First, minor phytotoxicity occurs, and the method of strengthening fertilizer and water management can be used to restore normal fertility of vegetables;
The second is to choose the right pesticide, especially the herbicide should be carefully applied;
The third is to keep the dosage and concentration of pesticides closed while avoiding repeated use of one pesticide;
Fourth, avoid mixing pesticides at will;
Fifth, the application of drugs should avoid high temperatures;
Sixth, the equipment that has been applied with the herbicide must be cleaned before it can be reused.
4, to rotate and change the vegetable cultivation environment
First, vegetables that are susceptible to eggplant, tomato, and melon are to be replaced with other vegetable varieties in different seasons or seasons;
Second, it is necessary to increase the application of organic fertilizer and improve the soil in greenhouses where multiple obstacles are likely to occur;
The third is to use soil heavy mites to inhibit the bacteria; the fourth is to address the lack of soil, and timely supplement the lack of nutrients.
Although the greenhouse cultivation method is simple and the yield is high, you still need to pay attention to the prevention and treatment of diseases. The above is the prevention and treatment method of the “four evils†in greenhouse vegetables. You can learn from them.
What is Vector 8D NLS?
The purpose of this training program is not a detailed physical justification of the principles of the «8D-LRIS» device, since different devices are designed differently. Currently, there are several manufacturers of this equipment, [spinoffs" from the original research group. In particular, in the original version of Russian, the headphones were used as magneto-inductors with an oscillation frequency, which is close to the thetarhythm of the brain, while in later versions of the device - as a conductor of electromagnetic waves that are close to the alpha rhythm of the brain. A good effect is obtained from the use of electromagnetic waves as a trigger mechanism for the study of a healthy body.Also, in many other versions of the device, laser emitters are used to affect the brain of the patient.Using the laser leads to an increase of the resonant response. However, there is a risk of adverse effects of such exposure, so the laser
emitter is not used in all models of «8D-LRIS» equipment.
Facts about the program:
Equipment set up on a modern element base, has a stylish design, and interfaces with a PC via USB-port. The unit LRIS-nls device has a digital trigger sensor in the unit and an analog trigger sensor which is built into the bio inductor.
The program works steadily on any Windows operating system (Windows operating system XP/Vista/7) New versions are available for free download from the site
Base standards greatly expanded and continue to grow A detailed user E-manual is included.
Assessment of the chakras and aura.
(An aura is the electromagnetic field that surrounds every living being and is manifested in the physical field by electrically charged objects that represent themselves as different colors that surround the body. This electromagnetic field can provide information regarding a person`s emotional state, the quality of consciousness and will determine the level of health regarding an individual organ and organ systems.)
8d LRIS NLS Range:
LRIS-NLS can be used by anyone who is interested in quickly and effectively examining the health of their patients, clients, friends, family or employees. Accurate analysis is the driving factor of our company and no matter whom you are or what you do, you will be well informed with the information you will gather from the LRIS-NLS device, and so will everyone you work with.
Remember that the information is being gathered on a cellular level, and the beauty of this method of diagnosis is that before anything is manifested, it is found.
People who fall under any of the following categories are welcome, advised and will find benefit in using and having a LRIS-NLS biofeedback device.
