The author believes that the following five aspects should be used to improve seedlings: through more formal channels, seedlings should be purchased from seedlings with high reputation and wide influence; the fresh color of trunk should be purchased and purchased. Plump, well-developed roots, long and well-distributed seedlings with lateral roots; timely planing seedlings, the shorter the time of planing, the less water loss, the higher the survival rate; pay attention to observe the branches, trunks, and roots for pests and diseases; Smooth seedlings.
Grasping seasons? Regarding planting seedlings, the author believes that late autumn and winter is the best season for planting trees throughout the year. The reason is that this time when the trees enter the dormancy stage, the sap will not stand still, and even if there is a root injury or skin contact, the unearthed planting will not cause serious problems. This stage generally uses bare roots to dry, which can effectively promote root germination and promote survival rate. Most people think that spring is the golden season for planting trees (different regions and different times). But the author believes that the spring tree sap begins to flow, and the spring wind is more, the climate is dry, and the water loss is too fast. Therefore, trees should be planted in the early autumn and winter. In addition, some green engineering units need to plant seedlings in summer, and according to many years of experience, the author believes that summer must bring soil ball, and can not bring leaves, so as not to affect the survival rate.
Seedling cultivation "eight character essentials"
First, "soil" soil is the key to seedling cultivation. The choice of soil and soil plays a crucial role in the quality of seedling growth. The author believes that it is better to choose loess and blister loess, with a certain amount of sandy soil. (If suitable for planting Phytophthora seedlings).
Second, "fertile" crops a flower, rely entirely on fertilizers. Seedlings are also the same, fertilization should be based on the production habits of seedlings, timely and appropriate fertilization. It should be based on the principle of "Ning less not much, rather not concentrated, rather shallow shallow, rather close to Ningyuan" principle. (such as Acacia, Farn, Scorpio, etc.).
Third, "water" water is the source of life for nursery stock. In the cultivation and management, the watering time and amount should be determined depending on natural conditions, climate change, and the characteristics of the trees. The author believes that "water is the life of seedlings, water is the disease of seedlings, and water must be sent to life." (e.g. Beijing Pelican, Huang Pei, etc.).
Fourth, the "species" of good varieties will inevitably bear fruitful economic results and create good results. Therefore, as an insider, they must update their concepts, gain insights into market conditions and market changes, and select breeds that are recognized by experts. (such as fast-growing Fatong, fast-growing white wax, North American jellyfish, etc.).
V. "Dense" refers to the dilute consistency of planted seedlings. As we all know, "two more than one", some people mistakenly believe that seedlings plant the same. To the author's opinion, planting seedlings should be based on the growth characteristics of seedlings, reasonable close planting, rather dilute not thick, so as to achieve a greater than two economic effects. (such as fast-burning wax, fast-growing Fong, etc.).
Sixth, the "protection" author believes that mainly for the purpose of drug pest control pest control measures, should seize a few key aspects: the timely application of bactericidal drugs, oviposition drugs, insecticides. According to different seasons, take morning or evening mixing or single application of drugs. According to the seedling species and morphology, different spray sprays are used. (such as white wax, sweet-scented osmanthus, flower shrubs, etc.).
VII. "Management" management is the focus of nursery stock cultivation. Management should highlight a "diligence" word, which is to manage "eyesight, footwork, handwork" in peacetime. Special management should take a fuss about management in windy days and rainy days. (such as fast-growing Fa Tong after the storm, fast-growing white wax, management of fast-growing countries, etc.).
Eight, "work" kind of crops say harvest, doing business talking about capital, planting flowers and trees is the same. Reasonable and appropriate use of "work" can achieve a multiplier effect. (If using machinery to improve work efficiency, reasonable use of labor, etc.).
To sum up: people pay attention to facts, work pay attention to letters. The cultivation of seedlings comes up with a fine word for "difficulty", and it is the last word to do good products and promote efficiency, to pull customers and retain customers.
Medical protective clothing refers to the protective clothing used by medical personnel (doctors, nurses, public health personnel, cleaning personnel, etc.) and people entering specific medical and health areas (such as patients, hospital visitors, personnel entering infected areas, etc.). Its function is to isolate germs, harmful ultrafine dust, acid and alkaline solutions, electromagnetic radiation, etc., to ensure the safety of personnel and keep the environment clean.
