Three-dimensional planting is to make full use of time, space and other aspects of planting (breeding) conditions to achieve high-quality, high-yield, high-efficiency, energy-saving, environmentally-friendly agricultural planting mode. The following is a description of greenhouse three-dimensional planting techniques of greenhouse tomato, lettuce and koji mushroom.

In early February, the Coprinus comatus rod was first buried in the middle of the cultivation pot, then the tomato was planted at a distance of 30 cm, and lettuce was planted on both sides of the tomato. The planting method makes full use of the land space. Coprinus comatus and lettuce do not occupy the growth space of tomato, and the carbon dioxide released by Coprinus comatus provides gas fertilizer for tomato and lettuce growth, while the oxygen released from tomato and lettuce is beneficial to the growth of Coprinus comatus. Mutual benefit. Every 667m2 increase the lettuce income by 2,000 yuan than the conventional tomato planting, and increase the income of 1500 yuan of the chicken leg mushroom. It is a new technology worth promoting.

1, chicken legs

The bag is planted, the raw material of the mushroom bar is cotton seed hull, 5% bran is added, the gypsum powder is 1%, the lime is 2%~3%, and the mixture is mixed and then fermented. When there is a large amount of white radiobacteria and accompanied by fragrance When it tastes, the piles are cooled and bagged. The bag is made of 17cm×35cm polyethylene tube bag, and the inoculum size is 10%~15%. The bag that has been sterilized can be filled with a bag at a temperature of 20 ° C to 25 ° C for 25 days. Before the ground, the mycelium-filled bacteria bag will be taken out of the plastic bag, which will become a mushroom stick. In the center of the tomato cultivation, the groove of 20cm wide and 15cm deep will be dug, and the head and tail of the mushroom stick will be connected into the ditch, and the bag will be covered. 3~4cm of wet soil, poured 2 times after 2~3d. When the hyphae grow out of the soil layer, properly cool down, try to create temperature difference, reduce ventilation, and strengthen humidity management. Under the condition of 10 °C ~ 22 °C, the mushroom can be produced in about 15d. During the growth period, the key is to ensure the humidity inside and outside the material, and the relative humidity of the air is stable at about 80%. Under normal circumstances, the chicken leg mushroom can receive 4~5茬. The standard of harvesting is not old, otherwise the chicken leg mushroom will turn black after opening the umbrella and lose its commercial character.

2, tomato

Selecting cold, disease-resistant varieties, such as Chery, the miscellaneous 9. 11 mid-planting seedlings, 2 minutes leaf stage seedlings, seedlings 8 ~ 10cm length. In early February bred seedlings with buds. Soil preparation before planting, 667m2 per 5000kg into the decomposition of organic fertilizer, compound fertilizer plus 25kg. Each row of 2 rows, the row spacing is 25cm × 65cm, after planting water, cover the mulch. When the film is covered, the growth area of ​​the Coprinus comatus is opened and spread on both sides of the clam. The tomato adopts a single dry pruning, leaving 2 to 3 ears per plant, leaving 4 to 5 fruits per ear. Since Coprinus requires a large humidity, require frequent watering or water, to guard against colonization early in excessive growth of tomato seedlings, planting the tomato strain per 667m2 by pouring 300 ~ 400g Aifeng spirit, with 30 ~ 40mg / L tomato dip Spirit Flowers to increase the fruit setting rate. The main diseases in the growth period include epidemic diseases and gray mold diseases. The disease prevention and control is prevented by the prevention and control of bactericidal bactericidal agents, and the gray mold is controlled by Suikeling.

3, lettuce

Choose loose leaf lettuce varieties, such as the United States big fast. Seedlings are used in early November, and the seedling temperature is controlled at 16 °C ~ 20 °C during the day and 10 °C at night. When 2~3 true leaves are used, the seedlings are divided into 6~8cm. Planted at the same time as tomato in early February. Take the method of water-stable seedlings, that is, planting the plants on both sides of the tomato noodles, and then planting the seedlings with shallow soil to stabilize the seedlings, watering the ditch, and then covering the soil to cover the soil. This can avoid the adverse effects of reducing the ground temperature and slowing down the seedling after full irrigation. Planting 1 row per side, plant spacing 25cm. In the growing period, chlorothalonil and mancozeb are used to prevent downy mildew.

Roughness Measuring Instrument

Roughness meter, also known as surface roughness meter, surface smoothness meter, surface roughness tester, roughness measurement meter, roughness tester, and other names. It has the characteristics of high measurement accuracy, wide measurement range, easy operation, portability, and stable operation. It can be widely used for the detection of various metal and non-metal processing surfaces. This instrument is a pocket instrument that integrates sensors and hosts, with handheld characteristics, making it more suitable for use in production sites. The exterior design is sturdy and durable, with significant resistance to electromagnetic interference, in line with current design trends.

The application fields of roughness meters include:

1. Mechanical processing and manufacturing industry, mainly metal processing and manufacturing. Roughness meters were originally developed to detect the surface roughness of machined parts. Especially, stylus type roughness measuring instruments are more suitable for detecting hard metal surfaces. For example, the automotive parts processing and manufacturing industry, the mechanical parts processing and manufacturing industry, and so on. As long as these processing and manufacturing industries involve the surface quality of workpieces, the detection application of roughness meters is essential.

2. In the non-metallic processing and manufacturing industry, with the progress and development of technology, more and more new materials are applied to processing processes, such as ceramics, plastics, polyethylene, etc. Some bearings are now made of special ceramic materials, and pump valves are made of polyethylene materials. These materials have a hard texture, and some applications can replace metal materials to make workpieces. During production and processing, their surface roughness also needs to be tested.

3. With the continuous strengthening and improvement of the technology and functions of roughness meters, as well as their in-depth promotion and application, more and more industries have been found to require roughness detection. In addition to mechanical processing and manufacturing, roughness evaluation is also required in the production and processing of power, communication, electronics, such as couplings on switches, integrated circuit semiconductors, and even stationery, tableware, and other products used in people's daily lives The surface roughness of human teeth needs to be tested.
