1, fertilizer and water management
Because melons have lower temperatures at the time of colonization and less water transpiration, attention should be paid to keeping warm and controlling watering after planting water. After planting until the first female flower before flowering, adhere to the soil to see dry see wet, usually 7 ~ 10d (days) pouring 1 water, sprinkle water too much, easy to form plant leggy, postponed results.
Do not spray water during the flowering period to prevent overspray formation and fruit drop. After the fruit is set, sprinkle more water as appropriate, usually 5 to 7 days (days), pour 1 water, stick to see the soil dry see wet. Watering was stopped 10 days before harvest (days), and no drought or watering occurred during the harvest period in order to improve the sugar content of the fruit as much as possible.
After easing the seedlings, the cultivator is divided into secondary cultivars and sprayed with the plant growth regulator Shuofeng 481 (natural alizarin lactone) to promote the healthy growth of the wheat seedlings. In the period of extension, ternary compound fertilizer with higher nitrogen content can be applied in conjunction with spraying. In the expansion stage of melon, 15kg of potassium sulfate and 20kg of potassium dihydrogen phosphate are applied per 667m2, and nutritious supply of melon is added to promote rapid fruit enlargement. In the growing season, 0.2% potassium dihydrogen phosphate can also be sprayed for 2 to 3 times to promote plant growth and fruit development.
2, pruning fruit
Muskmelon is dominated by Sun Man Guagua, which uses multiple vine pruning methods. When the main vine leaves are picked, they will be picked again when the vine grows to 7-8 leaves to promote the growth of Sun vines and flowering. Sun vines in the 4th section of the vine vine should be removed early. Leave melons, leaving 6 to 8 fruits per plant. After the young melons are sitting on, they will then take heart to Sun Man to promote the delivery of nutrients to the young melons and promote the expansion of the young melons. After sitting in the melon, obeying its beauty grows no longer pruning.
3, artificial pollination
Muskmelon is a dichogamous crop of the same sex. Because of the low temperature in the early spring and the lack of insects, artificial pollination is generally required to improve the fruit setting rate of melons. After the female flowers were open, when the temperature rose to 20°C in the daytime, male flowers that were open on the day were selected for artificial pollination. General pollination
After 7 days (days), when the young larvae reach the egg size, the melons are selected to remove the remaining flowers and young larvae.
4. Pest control
Use the combined prevention, control and skills of agriculture, physics, and chemistry to minimize the use of low-toxicity, high-efficiency, and low-residue chemicals to avoid the formation of phytotoxicity and environmental pollution. Use high ridge culture to cover up the mulch and try to prevent cultivation in low-lying areas. Hanging yellow and frequency-vibration insecticidal lamps in the field to trap and kill pests.
The main diseases of melon are powdery mildew, wilt disease, epidemic diseases, etc. Powdery mildew can be controlled with 2% antimycotic 120 (Nongkang 120) water 200 times or 1% Wuyimycin water 100 ~ 150 times; withered The disease can be controlled with 50% carbendazim WP 600 times or 50% benomyl WP 1500 times; the disease can be controlled with 72% urea MnZn (Kelu) WP 800 times. Every 7 to 10 days (days), spray 1 to 2 or 3 times.
The main insect pests are aphids, whitefly, etc. The aphids can be controlled with 10% imidacloprid WP 2000 times solution or 40% dimethoate EC 1000 times solution; whitefly can be used with 10% buprofezin (Pentacloprid) EC 1000 times Prevention.
5, harvest
After 25 to 30 days (days) after general pollination, the fruit matures and can be harvested when the melons are harvested. Try not to hurt the fruit when harvesting, to avoid affecting the value of goods and economic benefits.

What is the AHD Four in One CCTV Kit ? The AHD Four in One CCTV Kit/ AHD CCTV Kit/ AHD CCTV Kit HD/ AHD CCTV Kit Near Me/ AHD CCTV Kit Youtube/ AHD Kit AHD CCTV System is an importable part of the CCTV Kit, and this kind of CCTV Kit is also widly applied to the many fields.
So what about the advantages of the AHD Four in One CCTV Kit?
AHD Four in One CCTV Kit is the combination of the AHD Four in One Cameras and the Digital Video Recorder. Let me introduce you the 2 parts respectively.
The AHD Four in One Camera, also called the Analog High Definition Camera, one type of the analog camera, contains 4 video formats, and they are AHD,TVI,CVI,and CVBS respectively. The AHD Four in One Camera can transmit the ultra-long distant (500 meters) high-definition analog signal(resolution above 720P is High Definition, also called the HD ) via the ordinary video cable or the 75-5 coaxial cable.The AHD Four in One Camera adopts the advanced Y/C signal separation and analog filtering technology, which can effectively reduce color noise in the high-frequency area and improve the image restoration. Besides, compared with the traditional analog high-definition camera, the image resolution of the AHD Four in One Camera has a great improvement and the highest definition can reach up to the equal level to the network HD 1080P.
The Digital Video Recorder, also called the DVR, is the video storage device(a computer system for image storage and processing) via the hard disk recording. The Digital Video Recorder has the functions of long-term image recording, voice recording, remote monitoring and control of images/voices. In terms of the image processing, image storage, retrieval, backup, network transmission, and remote control, the Digital Video Recorder is the far superior to the analog monitoring equipment because of the adoption of the digital recording technology.
The Digital Video Recorder represents the developing direction of the TV monitoring system, and it is also the first choice for the TV monitoring system in this market.
What about the disadvantages for the AHD Four in One CCTV kit?
The AHD Four in One CCTV Kit is wired and it is not so convienient as the Wireless CCTV Kit in some applications, but the AHD Four in One CCTV Kit is stable and cheap in some degree.
Therefore, we should choose the suitable CCTV Kit according to our demand.
