Description

TECHNICAL FIELD

[0002] In the modern forestry seedling raising field, scientific and reasonable fertilization is very important to the healthy growth of seedlings, however, the current widely used seedling raising fertilization technology still has many deficiencies, these problems not only affect the fertilization effect and seedling growth quality, but also bring additional manpower and economic burden to seedling raising work.

[0003] Firstly, in the seedling greenhouse cultivation stage, the traditional fertilization method mainly relies on manual operation, the staff needs to carry heavy medicine cylinder, shuttles in narrow seedbed, and sprays liquid fertilizer to seedlings one by one, this method has many disadvantages: first, the manual operation intensity is big, the worker needs to carry heavy work for a long time, which is easy to cause fatigue and occupational disease; Second, the fertilization efficiency is low, and it needs to consume a lot of time and manpower to cover large area seedling raising area; Third, manual spraying can not guarantee uniformity, which may lead to overfertilization or insufficient fertilization in some areas; Fourth, long time contact with chemical fertilizer may cause potential threat to the health of workers, these factors comprehensively, not only increase the seedling raising cost, but also may affect the growth quality of seedlings and the whole seedling effect.

[0004] Secondly, in order to solve the limitation of manual fertilization, some seedling raising bases use fixed pipeline conveying system to spray liquid fertilizer in large area, this method improves the fertilization efficiency to a certain extent, but still has obvious deficiencies, mainly reflected in: first, the pipeline system design is simple, lacks flexibility, and can not be adjusted according to the characteristics and growth stage of different varieties of seedlings; Second, the conveying speed of liquid fertilizer is fixed, and can not be adjusted according to the actual demand, which may lead to too much or too little fertilizer for some areas or some seedlings; Third, it can not accurately control the spraying amount and spraying speed, which may cause fertilizer waste or uneven fertilization; Fourth, the fixed system is difficult to adapt to the change of seedling raising area layout or seasonal adjustment demand, the existence of these problems seriously limits the applicability and effect of the fertilization system, and can not meet the requirements of modern precision seedling raising.

[0005] In addition, in view of the above problems, some equipment manufacturers try to introduce adjustable mechanism in the fertilization system to realize flexible adjustment of the liquid fertilizer conveying speed, although this improvement can theoretically improve the adaptability of the system, but in practical application still faces many challenges: first, the adjustment mechanism is simple in design, and the structural stability is insufficient, it is difficult to withstand the test of long-term use; second, the vibration during equipment operation may cause displacement or loosening of the adjustment device, affecting the preset conveying speed; third, the impact force generated by the high-speed flow of liquid fertilizer in the pipeline may cause internal structure vibration, further aggravating the instability of the adjustment mechanism; fourth, the lack of effective protection and locking mechanism makes the adjusted setting easily disturbed by external factors and changed; the existence of these problems not only affects the accuracy and uniformity of fertilization, but also increases the difficulty and cost of equipment maintenance.
