Strawberry seedling breeding technology

<

First, soil selection Strawberry hi light and more shade-tolerant, shallow roots, not only poor drought resistance, but also a higher demand for soil fertility, suitable for cultivation in fertile, well-ventilated sandy loam soil.
Second, the choice of varieties currently used in the Fukang region production of high-quality, high-yield, cold-resistant, anti-dry heat, drought-resistant varieties of Dandong fruit, ghosts, anger and Gan.
Third, the breeding of seedlings using ramets ramets method, easy to operate, rapid breeding.
IV. Seedling preparation In the second half of the month, the soil is deep-cultivated. Each 667 square meters of fermented organic fertilizer is applied to 3,000 to 4,000 kg of organic fertilizer, 10 kg of diammonium and potassium sulfate, and the fertilizer is thoroughly mixed. Fine soil preparation, according to the terrain to do 畦, 畦 width of 1 ~ 1.2 meters, the length of the field may also be determined according to the amount of field seedlings to determine the nursery area, Daejeon per 667 square meters with seedlings 8000 ~ 10000 strains, in the whole field 667 square meters of trifluralin or acetochlor 80 ~ 150 grams, spraying 40 kilograms of water, followed by immediate arable land, pre-emergent weeding.
5. Planting mother plants will be planted in mid-April of April and mid-August of the fall. The mother plants with original species characteristics and no pests will be selected. The center of the crop is centered, and the spacing is 80-100 cm. The spacing is 30-40 cm. , 667 square meters colonization of 1600 to 2800, through the breeding of stolons, can be bred into about 40,000, for greenhouses 2688 square meters with seedlings. When planting, the stems and shoots of the seedlings should be flush with the topsoil, that is, it is appropriate not to bury the roots and not to expose the roots. The same variety is planted in a pod, and a variety of cultivars must be kept in the middle to maintain purity.
Sixth, nursery management
1. Irrigate the plant with water immediately after planting, and irrigate 1 small water every 3 to 4 days during spring planting; when the planting season is high, it is best to irrigate the water once a day or every other day, until the seedlings are replanted and the conventional management is performed. Fertility irrigation 8 to 10 times.
2. After cultivating and easing the cultivator, combine irrigation to carry out cultivating, weeding, and preserving hoeing. The cultivator should be shallow, and the cultivars should not damage the roots. During the breeding period, a total of 4 to 5 cultivators are used.
3. Apply topdressing urea and potassium sulfate 1 to 2 times during the entire growth period, 667 square meters, 10 to 15 kg, apply to a hole or furrow, spray 0.2% to 0.3% potassium dihydrogen phosphate or urea according to growing foliage. ~ 2 times.
4. In order to reduce nutrient consumption, we should remove the spoils from the mother plant in time. When the pods are produced in large quantities, artificial manure is used to press the vines to distribute the newly emerged stalks to each direction of the main stems in a uniform manner. Early hair roots, timely picking the heart after covering the stem stalks, and removing excess stems.
VII. Pest control In the high temperature and high humidity season in summer, it is easy to induce pests and diseases. Powdery mildew may be treated with triadimefon or thiophanate-methyl. Red spiders can be controlled alternately with konjac or liuyangmycin.
Eight, raising seedlings for storage in the spring, raising seedlings in mid-August, and raising seedlings in the fall, in April of the following year. Raised in the middle. When transplanting, it is best to transplant with soil and try to avoid root damage. Cut off the old leaves after the start of the planting. For example, for the Sinotrans or the unfinished seedlings, remove 2 old leaves, leave more than 5 cm of petioles, keep 2-3 leaves in cool place or leave in the sand, and do not put on the leaves when watering. Spray water and shading. The seedlings to be stored in winter should be bundled into small bundles and stored at a humidity of 60% at a temperature of -2 to 0°C. The cold in winter should be taken care of, and the next spring can be planted again.

Introduction:

Hydrogen-rich water cup, also known as water-element water cup, originated in Japan. According to Japanese medical research, active small molecule hydrogen can provide comprehensive anti-oxidant care for the body, specifically for metabolic function repair, immune regulation, eliminating inflammation, improving allergic constitution, preventing cell mutation (cancer prevention and anticancer), promoting tissue repair, anti-aging beauty and beauty.

At the same time, hydrogen is easier to dissolve in water after decomposition. We know that hydrogen is usually insoluble in water. Therefore, only after molecular refinement, can it be integrated into water to a certain extent and achieve the role of increasing the content of hydrogen molecule.

The principle of hydrogen rich water:
Bacteria and viruses invade the body constantly through the food and breathing, However the white blood cells can release reactive oxygen species to protect us. Reactive oxygen will attack human normal cells and DNA, The components of cells will be oxidized, This is the cause of disease, aging and spot.
Hydrogen rich water contains rich hydrogen molecules. it will be decomposed into hydrogen atoms after drinking. With the human body`s reactive oxygen species, oxygen radicals undergo a reduction reaction to generate the most harmless water that the human body needs most. The chemical reaction with oxygen is called oxidation reaction, and the chemical reaction with hydrogen is called reduction reaction. The research report confirms that hydrogen is colorless, odorless, non-toxic, and has no side effects.
Hydrogen is one of the best natural antioxidants, because the hydrogen molecules in the hydrogen-rich water are very subtle, can penetrate cells quickly, neutralize the human body`s [health killer" oxygen free radicals, and finally generate water to be excreted. Hydrogen is hardly soluble in water, but the use of nano-level technology can solve this technical problem. Each hydrogen atom will uniformly wrap water molecules, thus forming small molecules, which can pass through cell membranes because of their small size, to liminates malignant oxygen free radicals in cells.


Why can hydrogen water improve physical health?
As we all know, the human body is composed of cells, the human disease can eventually be attributed to the cell by Loss of human aging is due to cell aging or necrosis caused by. And cause cell disease sick old The main culprit is the excess oxygen free radicals. The main effects of oxygen are: antioxidant. A hydrogen atom Combined with reactive oxygen species, reduced to water, excreted.
Platinum and titanium alloy electrolytic tablets
The new technology allows water to evenly contain hydrogen molecules, to promote hydrogen and water to achieve a stable combination of hydrogen
High concentration, good stability characteristics.
