Description

A hydroponic device for cutting branches of forest trees

technical field

The invention relates to a liquid culture device, in particular to a liquid culture device for plant cutting and cultivation.

Background technique

Hydroponics is a new type of soilless plant cultivation, also known as nutrient liquid cultivation and hydroponic cultivation. Its core is to fix the plant roots in the planting basket and let the roots hang naturally into the plant nutrient solution. This nutrient solution can Instead of natural soil, it provides water, nutrients, oxygen, temperature and other growth factors to plants, so that plants can grow normally and complete their entire life cycle.

There are three main types of hydroponic facilities: 1) Nutrient liquid film hydroponics (NFT). Plants are planted in a shallow, flowing nutrient solution, and the roots are suspended to increase their oxygen uptake. Use a long and narrow black polyethylene film, place the grown seedlings and seedling blocks in a row according to the planting distance, then turn up the two sides of the film, fold it into a triangle with a metal wire, fix the upper mouth with a paper clip or a small clip, and put the nutrient solution in the Flow in plastic tank. The hydroponic facility is mainly suitable for growing lettuce, strawberry, bell pepper, tomato, eggplant, melon and other crops. 2) Deep flow hydroponics (DFT). It is a deep liquid flow hydroponic planting system with planting tanks made of cement bricks as the main body. It has the characteristics of low investment, convenient management, wide range of suitable crops, and can better solve the needs of the root system for oxygen. The nutrient solution is intermittently circulated between the planting tank and the underground liquid storage tank by using a water pump, a timer, and a circulation pipeline to meet the supply of nutrients and oxygen in the nutrient solution. 3) Floating Capillary Hydroponics (FCH): It consists of four parts: a cultivation bed, a liquid storage tank, a circulation system and a control system. The cultivation bed is connected by polystyrene board grooves with good heat insulation performance, and there is a floating board covered with wet felt inside the bed. The nutrient solution is controlled by a timer, flows through the cultivation bed through the pipeline and the air mixer, and returns to the liquid storage tank at the liquid outlet. This fully enclosed nutrient solution circulation is less affected by changes in the external environment, and the rhizosphere environment of plants has little change, and is suitable for the growth of various plants.

But it is worth noting that the hydroponic flowers produced in various countries in the world are not very satisfactory in terms of variety or quality. The most fundamental reason for this is that hydroponic flowers are susceptible to hypoxic stress and nutrient imbalance during the growth process, which leads to poor growth of hydroponic flowers such as rotten roots and yellow leaves, and the water quality deteriorates accordingly. Further influence the growth of hydroponic flowers and its ornamental value. Therefore, solving the balanced supply of oxygen and nutrients in the nutrient solution is the most critical link in the growth process of hydroponic flowers.

At present, there are many researches on plant hydroponics in China. A large number of existing hydroponic systems are used for hydroponic cultivation of seeds or tender seedlings of plants such as crops and flowers. For example, the patent number is ZL 87201208 utility model patent "Plant Nutrition Liquid and aerated hydroponic equipment", which includes hydroponic tanks, planting beds, liquid storage tanks, water-air injection aeration pumps, delivery pipelines and electronic time controllers. Fix the plant seedlings on the planting bed, and turn on and off the water-air injection pump according to the pre-programmed time sequence to make the nutrient solution circulate regularly, and automatically add gas to the nutrient solution during the cycle to make the dissolved oxygen reach saturation. Supply the nutrients and sufficient air needed by the plant roots for plant growth. Another example is the utility model patent No. ZL 200520062459.0 "Assembled circulating liquid supply planting device", which consists of three parts: circulating water supply and drainage system, planting pipe, and fixed bracket. The number of planting pipes is more than two, and multiple planting pipes are connected in parallel or in series with the water supply and drainage pipelines; the fixed bracket is assembled from an arrow-shaped frame welded by more than two square tubes and a number of fixed clamps. The planting tube is fixed on the support by means of a bolt connection through a fixing hoop. The planting device can be widely used in hydroponic planting demonstrations in gardens, and scientific and educational experiments in hydroponic planting in primary and secondary schools. Another example is the utility model patent No. ZL 201010160562.4 "a mobile hydroponic bed and hydroponic system". The hydroponic bed is installed with at least 4 rollers at the bottom of the fixed hydroponic bed. The hydroponic system includes a hydroponic room, the above-mentioned mobile hydroponic bed, an equipment control system, a nutrient solution deployment system, a liquid supply system, a liquid return filtration and disinfection system, and a real-time detection system. The hydroponic room is connected by a partition door. It is a greenhouse or greenhouse composed of a combination of multiple independent hydroponic rooms; at least two running tracks are laid on the ground of the hydroponic room along the length direction, and the tracks are parallel to each other; the hydroponic bed can be run on rollers. Move on track. The cultivation objects of the above-mentioned hydroponic device are small plants with roots such as seeds and tender seedlings. The space of the hydroponic tank is small, and it is impossible to install forest branches. In addition, it is impossible to simulate the development mode of tree branches growing obliquely at a certain angle on living trees, and long-term immersion may easily cause bacterial growth and anoxic rot at the end cuts of forest branches. In addition, the above-mentioned hydroponic system also It needs to be used under greenhouse conditions, and has high requirements for related supporting equipment.

The existing hydroponic method of cutting branches of forest trees is extensively operated. After the branches of the forest trees are cut off from the trees, they are moved into the greenhouse and directly inserted into buckets or porcelain vats, and the method of artificially injecting water into them is used for hydroponic cultivation. It must be operated in a greenhouse, and the old water in each bucket must be pumped out manually and then injected with new water to prevent the ends of the branches from rotting due to long-term soaking and lack of oxygen. Common pollutants cannot be removed in time. The branches stand vertically in the barrel, which is quite different from the growing environment of trees growing obliquely, which often leads to insufficient water supply at the top of the branches, and because the branches are upright, it is relatively difficult to collect and pollinate pollen, which is not conducive to later experiments research and related processing. The operation workload is heavy, time-consuming, laborious, large investment, high cost, and the hydroponic environment of each branch is relatively independent, it is difficult to achieve the unity of hydroponic conditions, which is not conducive to the comparative analysis of experimental research.
