After the emergence of sweet corn, it is necessary to check the seedlings in time, and if it is found that seedlings should be replanted in time. In the 3-leaf stage, strong seedlings were selected and transplanted to make up the seedlings. Transplanting should be carried out on rainy days or in sunny afternoons. Watering should be carried out in time after planting to shorten the time for seedlings to ensure survival.
2. Miao Dingmiao
Marrowling should be early, should be selected before the seedlings will take root, generally in the seedlings 3 to 4 leaves. If the seedlings are too late, the plants are overcrowded, shading each other, and competing for water and nutrients, which can cause the primary roots to grow poorly, thereby affecting the growth of the shoots. The principle of thinning seedlings is to weaken the seedlings, leaving strong seedlings; to go to miscellaneous seedlings, to keep the seedlings and seedlings of the same color; to disease seedlings, leave the healthy seedlings, and leave 2 seedlings per hole in general, usually in the 4 to 5 leaf phase, ie You can leave a single hole, remove the seedlings and weak seedlings. Dingling time is also sooner rather than later. In areas where there are serious land pests and plots, the number of seedlings should be increased and the time for seedlings should be delayed. However, it is not recommended to exceed 6 leaves at the latest. When setting seedlings, it is necessary to pay attention to roots and roots, to avoid the emergence of second seedlings. When setting seedlings, it is necessary to “go to four to stayâ€, that is: to weak seedlings, retain strong seedlings, go to size seedlings, leave Qimiao seedlings, go sick seedlings, leave healthy seedlings, go to mixed seedlings, leave pure seedlings.
Precautions: Spleen and Ding should be carried out on a sunny day.
3. Weeding and weeding
Seedling during the cultivating period can loosen the soil and promote root growth; second, it can eliminate weeds, reduce nutrients and water consumption, and promote seedling growth. In the general seedling stage, two cultivators can be carried out. Before the first cultivating, the middle cultivator is used for the shallow cultivating at the 3 leaf stage, and the depth is 3 to 4 cm. At this time, the seedlings are short and the seedlings are to be avoided. The second time before the jointing stage, combine the soil with cultivator, and the cultivator depth should be 6-8 cm. The cultivator weeding should pay attention to the seedlings next to the shallow ploughing, so as not to hurt the seedlings, the lines can be slightly deeper.
4. Maize seedlings
According to varieties, density, soil fertility flexibility, general dark green leaves, fertilizer, high density, full of sensation of the seedlings of the seedlings; seedlings are not thin, thin, dry weak seedlings. Therefore, there are "three and three non-stop" farms. That is, the black is not yellow, and the fat is not thin, and the wet is not dry. Seedlings should generally end before the jointing, the time is too short to be effective, too long affect the spike differentiation, the formation of "small old seedlings." After the seedlings are over, they should immediately top-dressing and watering to promote growth.
5. Seedling fertilizer
Fertilizers at the seedling stage have functions of promoting roots, strengthening seedlings, promoting leaves, and strengthening culms. Usually in the 4 to 5 leaf stage after the Dingmiao, combined with cultivator Xiaotu soil topdressing, applied per acre 4 to 6 kg of urea, potassium chloride 5 to 7 kg.
6. Moisture management
Sweet corn needs less water at the seedling stage, but from the time it is sown to its emergence, it is necessary to keep the soil moist and promote germination. In case of drought, dry seeds, germination, etc. will often occur, causing serious seedling deficiency, so drought should be timely Watering. However, after emergence and before jointing, relatively less water is needed to keep the upper layer loose and dry, and the lower layer is moist. Sweet corn is not resistant to seedlings throughout the seedling period. In the event of rainy days, especially during the seedling period of sweet corn in autumn, it is necessary to pay attention to timely drainage to prevent flooding and induce pests and diseases in the field.
What is the pet scanner?
[Pet Scanner] involves high-tech innovation projects of medicine, bio-informatics, electrical engineering and other sciences. Using the quantum medicine as the theoretical basis, it applies the advanced electronic equipment to collect the weak magnetic field of animal cells for scientific analysis, thereby analyzing and determining the tested animal's health status and main problems and
putting forward standard prevention recommendations. [Pet scanner] is individualized guide of health care consultation for full animal body and forward health science, and has the advantages of completeness, non-invasiveness, practicality, simplicity, fastness, economy, easy popularization, etc. With the depth and development of scientific research, it will make a greater contribution for the cause of animal health, having a broad development and application prospect.
Principle of quantum analyzer:
The animal body is the aggregates of a large number of cells which are in continuous growth, development, differentiation, regeneration and apoptosis, and the cells constantly self-renew through its own division. In the process of cell division and growth, those charged bodies of atomic nucleuses constituting atoms as the basic unit of cell and the electrons outside the nucleus are in constant high-speed movement and changing, thereby constantly emitting electromagnetic waves.
The electromagnetic wave signals emitted by the animal body represent the specific state of the animal body, and the emitted electromagnetic wave signals are different under the different conditions of the human body, such as health, sub-health, disease, etc. If we can determine these specific electromagnetic wave signals, we can determine the status of the body's life.
Quantum medicine considers that the most fundamental reason of falling sick is that the spin of electrons outside the atomic nucleus and the orbit change, thereby causing the change of atoms constituting a material, the change of small biomolecules, the change of big biomolecules, the change of all the cells and finally the change of organs. Because the electron is a charged body,
when the spin of electrons outside the atomic nucleus and the orbit change, the electromagnetic wave emitted by the atoms will change. The energy o f the electromagnetic wave changes caused by the changes of the animal body's diseases and physical changes in the nutritional status is extremely weak and usually is only nano gauss to microgauss. The frequency and energy of the
weak magnetic field of hair determined directly or by holding a sensor compare with the resonance spectra of standard quantum of diseases and nutrition indicators set in the instrument after the frequency and energy are amplified by the instrument and processed by the computer, and then the corresponding quantum value being from negative to positive is output. The size of the
quantum value indicates the nature and extent of the disease and the nutrition levels. Finally, the test results are resolved by clinicians. It's similar to the principle of listening to broadcasting from the radio. There are many radio waves in the air. If you want to listen to some designated broadcasting, you can transfer the radio to the corresponding frequency, at this moment, resonance occurs, so that you can listen to this broadcasting. Quantum resonance uses this principle for testing.
