Chinese kiwifruit rooting seedling raising technology

Chinese kiwifruit is propagated using the root cutting method, simple, rapid breeding, and high survival rate. The following is a brief description of its technical points:

1. Site preparation: Choose sandy loam soil, apply 2,500 kg of compost per acre, deep-dump 40 cm, make a thorough plan, and make it 0.5 meters wide.

2. Cutting: In late March, dig a root cutting, it is best to dig with the plug. The root thickness of cuttings should be 0.3 cm or more and 8-10 cm in length. Put the water in the pot before the cuttings, press the 8-10 cm row spacing, then cover the soil 0.5-1.0 cm, and often spray moisturize.

3. Seedling shading: After emergence, take a low shading arbour south of north and a height of 1.2-1.5 meters. Shed cover straw, daytime cover, night exposing; sunny cover, cloudy exposing. After the beginning of autumn, the grass curtains were removed and only a small amount of grass was left on the roof so that the shade on the ground reached 70%. After entering September, the arbours can be removed.

4. Top-dressing: After the seedlings grow to 2-3 true leaves, they can be sprayed with 0.5% urea to raise the seedlings. Afterwards, spray water is used to increase the air humidity, and potassium dihydrogen phosphate and urea are sprayed every 15-20 days. Alternate spraying of fertilizers.

Hormone:

A chemical substance produced in the body that controls and regulates the activity of certain cells or organs. Many hormones are secreted by special glands, such as thyroid hormone produced by the thyroid gland. Hormones are essential for every activity of life, including the processes of digestion, metabolism, growth, reproduction, and mood control. Many hormones, such as neurotransmitters, are active in more than one physical process.

Endocrine:

Pertaining to hormones and the glands that make and secrete them into the bloodstream through which they travel to affect distant organs. The endocrine sites include the hypothalamus, pituitary gland, pineal gland, thyroid, parathyroids, heart (which makes atrial-natriuretic peptide), the stomach and intestines, islets of Langerhans in the pancreas, the adrenal glands, the kidney (which makes renin, erythropoietin, and calcitriol), fat cells (which make leptin). the testes, the ovarian follicle (estrogens) and the corpus luteum in the ovary). Endocrine is as opposed to exocrine. (The exocrine glands include the salivary glands, sweat glands and glands within the gastrointestinal tract.)
