[field selection]
The wax gourd should not be planted continuously on the same land, nor should it be planted on low-lying land. More fertile and neutral soils should be chosen for cultivation. Late winter melons are generally sown in June-July, and about 200 grams per mu are used.
Age transplanting
When the winter melon seedling age reaches 30 days and grows with two leaves and one heart, the strong seedlings with well-developed roots, short thick stems, thick leaves, thick and thick leaves, and no damage are selected for transplanting. Generally, only 800-900 mu are planted in the main vine, 400-500 mu are planted in two vines.
[Appropriate top dressing]
The principle of top dressing of late wax gourd is "pre-light, medium-heavy, late filling". After the seedlings are planted and live, they catch about 20% of the excrement and 100 kg of excrement. When the melon grows to 4-5 kg, the point is 4-5 kg ​​of urine or 0.1 kg of urea. When the melon grows to 15-20 kg, Points to recover human excrement 5-6 kg or urea 0.2 kg. If the leaf color fades afterwards, fertilizer can be applied to 2-3 kilograms of human waste per hole. When the melon vine grows to 1 meter in length, the cultivator once.
ã€Pruning vines】
Pruning is an effective measure to increase production and ensure the consistency of melon size. Generally left the main vine cultivation, when it grows to 20-24 leaves, began to stay in the melon, the former melon should be removed; leaving the two vine cultivation, the main vine to stay with the melon position, the side vines can not be less than 10 Leaf, young branches of the melon were all cut off to facilitate the growth of nutrients for the growth of young melons.
ã€Assisted Pollination】
Artificial pollination can improve fruit setting rate. Select the male flower that has just opened in the morning to remove the corolla and gently apply the anther to the female styling head.
ã€Pest Control】
The major diseases and diseases that occur in late melons include damping-off, wilt disease, epidemics, and worms and ticks. Resistance to phlegm can be controlled by 75% chlorothalonil 1000 times solution or 70% dexamethasone WP 1000 times solution; 50% carbendazim 500 times solution or 900 times 20% chlormethestin can be used to prevent fusarium wilt Liquid control; Epidemic disease can be used 75% chlorothalonil 600 times or 50% methemosulfide wettable powder 600 times liquid spraying leaves or irrigation roots, each irrigation 0.3-0.5 liters, 10 days or so irrigation, even defense 2-3 The effect is good; anti-miticide 55 with 40% dimethoate 800-1000 times or 90% crystal trichlorfon 1000 times. For control of earthworms, 50% phoxim 1000 times liquid or 1000 times liquid trichlorfon root can be used.
Various Vehicle Monitoring Systems
We have already understood some of the in-vehicle system products in the introduction to the classification of in-vehicle monitoring systems, and now let's take a closer look at various IVMS.
Sanan Techonology mainly concentrates on the Vehicle Monitoring Systems.fleet management system.fleet management device.fleet management software.fleet management product.Fleet Monitoring System. In Vehicle Monitoring System. Truck Monitoring System.Vehicle Security Camera System. Van Camera System for the vehicles for some special purposes, such as trucks, buses, tanker trucks, school buses, cold chain cars, police cars, taxies, Bank money transport trucks, cargo trucks, etc., not including the private cars.
So why these vehicles need a whole set of Vehicle Monitoring System to monitor, while private cars don't need this kind of complicated systems? Here are some reasons as follows:
1. Private cars just need normal monitoring functions that the normal monitor devices can reach; while these vehicles have special purposes, and these purposes need more specialized monitor devices to realize;
2. Vehicle Monitoring Systems integrate cameras, MDVR, web system, and monitor management system, are much more specialized, stable, and muti-functional, which can make passagers and goods or something safer;
3. A whole set of Vehicle Monitoring System costs much more than normal single monitor devices, generally speaking, if there is no special monitor purpose, there is no need to intall a whole set of car Monitoring System for private cars;
