Problems solved by technology

From a global perspective, the application techniques of soilless cultivation in the field of vegetables and flowers are quite mature; but the application of soilless cultivation to large and medium-sized woody (such as shrubs and small trees, etc.) plants is only in the experimental stage. The technology of removing the soil and transplanting it into pots to make it survive for a long time is not yet mature, and there is still a long way to go before mass production
[0004] In addition, with the development of people's aesthetic needs, the demand for plants such as large and medium-sized shrubs and small trees (such as bonsai production, etc.) The reasons for poor root growth caused by growing in pots with limited space for a certain period of time. It is difficult for various tree stump bonsai to survive long-distance transportation away from the soil, which affects their off-site transactions and import and export, etc.

Embodiment 1

[0045] Present embodiment is that the plant nutrient solution of the present invention is used for the soilless cultivation of Begonia chinensis (Rosaceae Chinensis plant):

[0046] The operation process is shown in Figure 1, and the specific method is as follows:

[0047] In mid-June, 2006, the inventor dug out 20 strains of Begonia chinensis with a plant height of 1.5m and a diameter of breast height of 3 to 5cm from the field, washed the root soil with a large amount of clear water, and treated corresponding diseases and insect pests (white powder disease, acarids, gram worms, etc.), soak the roots with 100ppm naphthaleneacetic acid solution for 10 hours and then transplant them into flowerpots with vermiculite and perlite (2:1) as the substrate; pour the plant nutrient solution of the present invention, the first time Irrigate thoroughly, thereafter water once a week the plant nutrient solution of the present invention of 2000~3000ml to guarantee the growth needs of plant....

Embodiment 2

[0058] Present embodiment is that the plant nutrient solution of the present invention is used for the soilless cultivation of golden marble (Pysimmonaceae persimmon plant):

[0059] The operation process is shown in Figure 1, and the specific method is as follows:

[0060] In March, 2006, the inventor was 0.5m in plant height, and after digging out 20 golden marbles with a diameter at breast height of 5 to 7cm from the field, the root soil was washed with a large amount of clear water, and treated by corresponding diseases and insect pests (using Wanling , Jishineng, Admiralty and other insecticides), then soak the root for 10 hours with 100ppm naphthalene acetic acid solution, then transplant it into a flowerpot with vermiculite and perlite (2: 1) as the substrate; water the plant of the present invention The nutrient solution is poured thoroughly for the first time, and then 3000-4000ml of the plant nutrient solution of the present invention is poured once a week, and after...

Embodiment 3

[0071] Present embodiment is that plant nutrient solution of the present invention is used for the soilless cultivation of red plum (Rosaceae Prunus plant):

[0072] Its operation process is as shown in Figure 1, and concrete method is the same as the soilless cultivation method of gold marble among the embodiment 2.

[0073] A total of 20 red plums were cultivated, the plant height before transplanting was 1.5m, and the diameter at breast height was 5-7cm.

[0074] Results: 18 Hongmei plants have survived till now, the survival rate is 90%.

[0075] The formula of plant nutrient solution that present embodiment is used for watering red plum is as follows:

[0076] The weight of each component contained in this plant nutrient solution of every 5000ml is respectively:

[0077] A large number of elements: potassium nitrate 10g, calcium nitrate 1g, magnesium sulfate 1g, ammonium phosphate 5g, potassium sulfate 4g, potassium dihydrogen phosphate 0.5g,

[0078] Trace elements: d...

This invention also discloses a utility scheme in large and medium scale woody plant soilless culture.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a plant nutrient solution and its application in plant cultivation. Background technique [0002] The nutrient solution can provide a variety of nutrients for plant growth; especially for soilless cultivation plants, the nutrient solution is the main source of nutrient elements that are indispensable for their growth and development. [0003] Soilless cultivation refers to the cultivation method that uses inorganic nutrient solution instead of soil to provide plants with the necessary nutrients for growth and development. Sun Xia from Shandong University of Technology pointed out in the article "Development Status and Trends of Soilless Cultivation Technology" that in 1985 the national soilless cultivation area was only 7hm 2 (ha), developed to 50hm in 1995 2 , about 315hm by 2005 2 , most of which are applied to vegetable production, and only a small part are applie...
