Cucumber summer and autumn planting
The varieties are selected from Ningfeng No. 4, Jinza No. 2, Jinlu No. 4, Jinchun No. 5, and Jinyou No. 40, which are heat-resistant, moisture-resistant and disease-resistant, and are suitable for summer and autumn cultivation.
Sowing of the whole land from mid-June to late July, the selection of plots with high topography, convenient drainage and irrigation, fertile soil, and no melons in the front. 5 days before sowing, 2000 kg per mu, 60 kg of compound fertilizer (nitrogen, phosphorus and potassium content greater than 30%). After fertilization, the soil is sorghum, the width of the ridge is 2 meters, the depth of the gully is more than 40 centimeters, and the bottom water is poured after the gully. Seeding in large and small rows, 70 cm in large row spacing, 50 cm in small row spacing, 25 cm in hole spacing, 3 to 4 seeds per hole, and 4000 plants per acre. Cover the sub-soil after sowing, cover the sunshade and prevent rain.
Remove the shading net after the seedling management. 1 leaf 1 heart time seedlings, two seedlings per hole, 3 leaves and 1 heart time seedlings, 1 plant per hole. 1 leaf 1 heart, 2 leaves 1 heart, 3 leaves 1 heart, respectively, apply dilute water to raise seedlings, 4 leaves and 1 heart, apply a little thick manure, and apply tying vines after fertilization. 4 leaves 1 heart after the appropriate control of water control fertilizer.
After the results, the results should be fertilized and watered. Generally, the fertilizer is applied 5 to 6 times, and each time a mu of 4,000 kg of manure water or 5 kg of urea is applied per acre, and water is applied after fertilization. The side vines are all retained.
The main control of pests and diseases are blight, blight and downy mildew. The control of wilt disease can be sprayed with 70% dikesone 800 times solution or 20% gram bacteria 800 times solution. The downy mildew can be sprayed with 58% syphilis 600 times solution, 72% gram dew 750 times solution, 70% methyl thiophanate 800 times solution. The control of the disease can be sprayed with 58% syphilis 600 times solution, 75% chlorothalonil 600 times solution, or 70% dikesone 1000 times solution. The main pests are cucumber and melon. The yellow stalk can be sprayed with 1000 times of trichlorfon or 1000 times of dimethoate. The control can be sprayed with 50% Kulong 800 times solution, 50% chlorpyrifos 1000 times solution, and Bacillus thuringiensis preparation.
After harvesting cucumbers at the right time, choose to harvest before 8 am. Harvested the next day during the harvest period.
Roughness profiler all-in-one machine is an all-in-one machine for measuring profile shape and surface roughness, which has the powerful function of analyzing and measuring profile shape and surface roughness. Realize accurate measurement of dimensions, shape and roughness. It is mainly used to measure the parameters of the surface micro-geometry and macro-geometry of mechanical parts such as straightness, inclination, angle treatment, roundness treatment, double-groove treatment, double-arc treatment, etc.
Performance characteristics
1. High accuracy, high stability and high repeatability: meet the measurement accuracy requirements of the measured part.

2) Independently researched and developed high-precision grinding guide rail system, which has good wear resistance of guide rail materials and ensures stable and reliable operation of the system;
3) High-performance linear motor drive system ensures high measurement stability and good repeatability.
2. Intelligent management and detection software system:
The operation interface of the instrument is friendly, the operator can easily master the operation of the instrument, and the use is very simple.
1) The company has accumulated many years of practical measurement software design experience to provide customers with simple, practical and fast operation experience;
2) The company has invested many years of human resources in the development of instrument software, with special software copyright;
3) With powerful functions, it can automatically process data, print reports in various formats, and automatically display, print, save and query measurement records;
The data can be archived or printed in a centralized manner, which does not take up the verification operation time;
4) The measurement range is wide, which can meet almost all types of workpiece profile measurement, including special measurement functions of special workpiece screw, bearing, thread and other profiles;
5) The measured section can be selected automatically and manually for evaluation, and software functions can be customized according to customer requirements;
6) Powerful CNC automatic measurement and automatic labeling analysis function;
For large quantities of the same type of workpiece, it can carry out CNC measurement, automatically analyze and process the data, and carry out SPC statistics on the data, and can carry out statistical analysis in various ways to give quality control guidance;
7) It can automatically record and save all verification results by using computer large-capacity database storage.
3. It can also measure surface roughness and contour shape
With the same main body, you can only switch different modules to measure the profile shape and microroughness of the product.
4. Multi-parameter evaluation
The roughness can be automatically evaluated according to different standards, including Ra, Rp, Rv, Rz, Rt, Rmax, Rq, Rsk, Rku, RSm, RPc, Rdq, Rdc, Rmr and P parameters, W parameters, Motif parameters, Rcore parameters and other multi-parameter evaluation.
5. Thickness parameter measurement
When measuring the roughness parameters, the height and thickness of some film steps within 600 microns can be measured simultaneously. The measurement is convenient, and the accuracy is controlled within 2% H (H, the total height of measurement). It is especially suitable for high-precision measurement occasions without scratches.
6. Measuring force system:
With the voice coil motor force measuring system, the force measurement can be continuously adjustable from 10 to 150 mN, and the force measurement resolution can reach 0.2 mN; It avoids the force measurement error caused by the vibration of the surrounding environment when the old weight is loaded, and reduces the measurement error caused by the change of the force measurement.
7. Intelligent protection system:
The instrument is protected by hardware and software in all directions, which can effectively protect the instrument host and probe, and reduce the probe and instrument damage caused by personnel's operation errors.
