环闭群流滴灌配制施肥系统Closed group flow drip irrigation compound fertilization system

技术领域technical field

本实用新型涉及一种农业、林业、园林、温室用滴灌浇水、施肥配制装置，尤其涉及一种环闭群流滴灌配制施肥系统。 The utility model relates to a drip irrigation watering and fertilization preparation device for agriculture, forestry, gardens and greenhouses, in particular to a closed-loop group flow drip irrigation preparation fertilization system. the

背景技术Background technique

我国设施农业发展迅猛，但是管理水平与荷兰、以色列等国家相比，存在很大差距，主要表现在： my country's facility agriculture is developing rapidly, but compared with the Netherlands, Israel and other countries, there is a big gap in management level, which is mainly reflected in:

1、滴灌产品浇灌水不均匀；目前，设施农业盆栽植物灌溉有一部分采用滴灌，即在每个花盆基质中插入一个滴箭灌水器，灌水时滴箭灌水器只能湿润滴箭周边的基质，整盆基质不能全部湿润。由于基质渗透性大，在重力作用向下，灌溉水往往从盆底部直接排出，不利于植物根系的生长，导致灌溉水极大浪费，降低水的利用效率。 1. The irrigation water of drip irrigation products is uneven; at present, part of the irrigation of potted plants in facility agriculture adopts drip irrigation, that is, a drip irrigation device is inserted into the substrate of each flower pot, and the drip irrigation device can only moisten the substrate around the drip irrigation when watering , The whole pot of substrate cannot be completely wet. Due to the high permeability of the matrix, the irrigation water is often discharged directly from the bottom of the pot under the action of gravity, which is not conducive to the growth of plant roots, resulting in a great waste of irrigation water and reduced water use efficiency. the

以往安设滴头的管路是从一端到另一端安设滴头，安设了滴头的管路内的起始端与末端的水压和水流有差异，不能保障每个滴灌点实现恒定的浇灌，同时也难以控制每个滴灌点的浇灌量和施肥量，不适宜规模化生产。 In the past, the dripper pipeline was installed from one end to the other. The water pressure and water flow at the beginning and end of the pipeline installed with the dripper are different, and it cannot be guaranteed that each drip irrigation point can achieve a constant It is also difficult to control the amount of irrigation and fertilization of each drip irrigation point, which is not suitable for large-scale production. the

2、人工施肥，效率低，利用率不高。设施花卉对营养液的要求比较高，花卉品种不同，生育期不同，营养液配方和施肥量也不一样。目前，主要采用人工配制营养液，通常是凭经验把花肥和水按比例混合，搅拌均匀，然后用一壶一壶浇灌。这种施肥方式劳动强度高、工作效率低，不适宜规模化生产。 2. Artificial fertilization has low efficiency and low utilization rate. Facility flowers have relatively high requirements for nutrient solution. Different flower varieties, different growth periods, nutrient solution formula and fertilization amount are also different. At present, the nutrient solution is mainly prepared artificially. Usually, the flower fertilizer and water are mixed in proportion according to experience, stirred evenly, and then watered with one pot after another. This fertilization method has high labor intensity and low work efficiency, and is not suitable for large-scale production. the

综上所述，我国现有的设施农业(温室、大棚)蔬菜、花卉等作物的灌溉和营养液施肥不能满足设施农业的发展，很难大面积推广，时效性差，费工费时，水肥浪费严重，作物产量低，品质差，工作效率低，不适宜规模化生产。 To sum up, the irrigation and nutrient solution fertilization of vegetables, flowers and other crops in my country's existing facility agriculture (greenhouses, greenhouses) cannot meet the development of facility agriculture, and it is difficult to promote in a large area, with poor timeliness, labor and time, and serious waste of water and fertilizer. , low crop yield, poor quality, low work efficiency, not suitable for large-scale production. the
