Vegetable intensive seedlings provide high-quality, uniform seedlings for vegetable production, which is an important measure to achieve standardization of vegetable production. At present, it is mainly based on seedling raising methods, in which sowing is the key technical link of seedling raising, and manual seeding takes time. Labor and other characteristics, and uniformity is poor, the application of seeding machine seeding is an inevitable trend. Through several years of experimental demonstrations, Henan Province has cultivated large-scale seedling raising bases, basically mastered the seedling raising technology of main vegetable varieties, and at the same time, combined with relevant units, carried out experimental demonstrations on the introduction and development of vegetable seeding seeding machines, and made progress in stages. At present, the large-scale seedling raising enterprises have gradually replaced the manual sowing, especially the development and demonstration of the sowing line, which has better solved the bottleneck of the fine seeding technology of the plug tray, greatly improved the production efficiency, improved the product quality and reduced the quality of the factory seedlings. The production cost has laid a good foundation and is conducive to promoting the rapid development of vegetable intensive seedlings in our province and even the whole country. The main type of seeding screening machine is now introduced as follows.

Nursery seeding machine type
According to the characteristics of the seedling seedling planter, the current principle is vacuum adsorption. There are three types of needle-type seed drills, needle-type precision seeders, and air-suction tray seedlings. According to the degree of automation, there are Handheld, semi-automatic, fully automatic assembly line three types.


1. Needle plate nursery seeding machine
It is a desktop structure, small in size, easy to move to the field, and has its own pneumatic system. It has automatic line-casting function. It is suitable for all kinds of plugs. It can make naked seeds or pelletized seeds. The working efficiency is 40 holes. /hour, 160 holes for 100 disks / hour.
Second, needle precision seeding seeding machine
It is a computer-controlled mechatronics modern gardening equipment. It adopts the working mode of negative pressure suction and positive pressure blowing, which can precisely control the row spacing, row number and seeding quantity of the tray. The number of seeding per hole is 1 -6 tablets, which can be determined by the user's own program, so that all the punching and sowing can be automated, and there are 9 kinds of needles of different specifications, suitable for broadcasting all kinds of naked seeds, and suitable for broadcasting small seeds such as begonia, tobacco and rape. Suitable for any type and specification of the tray, the seeding speed is 200 trays / hour.
Third, the air suction type seedlings seedlings nursery seeding machine
The planter adopts the working principle of negative pressure suction and whole plate sowing, which can conveniently complete the two steps of the substrate soil pit and seeding of the seedling seedling, by replacing the different types and different specifications of the suction plate, and different specifications. The nursery seedlings are adapted to meet the requirements of seeding precision seeding of different crops such as rice, vegetables, cotton, rapeseed and flowers. The outstanding advantages of the machine are negative pressure suction, hole-guided filling, high filling rate, and the whole plate can be sown for 1 hole, the performance is stable, and the working efficiency is 120-180 disks/hour.
