Description

Liquid storage device for nutritive trees

Technical Field

The utility model relates to a forestry afforestation technology is equipped, especially a can prolong dry season nursery stock survival time, improves the nutritive trees of afforestation survival rate and uses and hold liquid device.

Background

The effective rainfall capacity of arid or semiarid regions is small, the soil is desertified and barren, the conservation capacity is poor, and the recovery of forest vegetation in the regions through afforestation is the primary task of forest development. The roots of newly transplanted seedlings in barren mountain afforestation can be damaged in different degrees, so that the water absorption capacity is weakened, and the physiological metabolism of the seedlings can be ensured to survive only by having sufficient water and nutrients. Before the seedlings survive and root and before the seedlings are strong, enough water and nutrients are needed to be ensured in the soil, otherwise, the trees are extremely easy to die. In the past, barren mountain afforestation in arid areas can only adopt water delivery to ascend, which not only needs to consume a large amount of manpower and material resources, but also has the problems of water source fatigue, difficult irrigation and the like. At present, in order to solve the problem of supplying water, nutrients and the like to trees during drought, some high molecular polymer water retention agents are filled in nursery stock pits for afforestation. Although the water-retaining agent can quickly absorb a large amount of water, the water-retaining agent has limited capacity of controlling water evaporation and cannot store water for a long time, so that the survival time of newly planted seedlings is only 15-20 days when no effective water supply (drought) exists, and the survival rate of afforestation is only 30-40% generally.

Disclosure of Invention

The utility model discloses a solve the above-mentioned technical problem that prior art exists, provide a can prolong dry season nursery stock survival time, improve the nutritive trees of afforestation survival rate and use and hold liquid device.

The technical solution of the utility model is that: a liquid storage device for vegetative trees is composed of a tank body with a trapezoidal longitudinal cross section, a top cover with water retaining ring, and water collecting holes with filter cloth.

The utility model discloses can be when afforestation the landfill in hole cave bottom and nursery stock root ball lower part, be convenient for collect the rainwater and hold in jar internal, can mix with the nutrient solution that the internal preset of jar with nutrition trees. The utility model discloses can effectively avoid water evaporation too fast, for stretching into jar internal trees fibrous root through the water catch bowl and provide nutrition lastingly, prolong the survival time (30 ~45 days) of newly planting the nursery stock when no effective feedwater, make the nursery stock safety spend the arid season to improve afforestation survival rate and survival rate to 95~ 100%.

Detailed Description

The utility model discloses a nutrition trees are with holding liquid device is shown in figure 1, has a jar body 1, and the longitudinal section of jar body 1 is trapezoidal for big-end-up, and jar mouth of jar body 1 is greater than the tank bottoms promptly. The upper end of the tank body 1 is provided with a sealing top 2, the sealing top 2 is provided with a water retaining ring 3, the sealing top 2 positioned at the inner side of the water retaining ring 3 is provided with a water collecting hole 4, and the water collecting hole 4 is covered with filter cloth 5. The tank body 1, the capping 2 and the water retaining ring 3 are formed by welding and pressing cold-rolled thin iron sheet materials, and can be automatically degraded after being oxidized. The filter cloth 5 is made of non-woven fabrics, so that silt can be blocked and fibrous roots of trees can penetrate conveniently. Nutrient liquids (transplanting nutrient solution, strong seedling nutrient solution and the like) required by tree transplanting are filled in the tank body 1, and at the moment, the water collecting hole 4 of the tank body 1 is sealed by a pop-top hole cover to be beneficial to transportation and is convenient to open when in use. The water collecting holes 4 are small in diameter, so that the requirement that fibrous roots stretch into the water collecting holes and rainwater flows into the water collecting holes is met, the water is effectively prevented from being evaporated at an excessive speed, and the water supply period is prolonged.

When the hole is used for planting seedlings and afforesting, the easy-to-pull hole cover of the utility model is pulled open and buried in the bottom of the hole. The quantity of the landfills is determined according to the site conditions of the forestation land of the engineering project, and the quantity of the tank bodies is properly increased when the site conditions of the forestation land are poor. When the soil is filled to be level with the tank body 1, the nursery stock is put in, the nursery stock root ball is stably seated, and the soil is righted to be filled and planted, so that the capping 2 of the utility model is positioned at the lower part of the nursery stock root ball. The water retaining ring 3 and the capping 2 can form a water collecting tank, so that rainwater can be collected conveniently and stored in the tank body 1 through the water collecting hole 4; as the plant root system has water-directing property, the fibrous roots of the trees extend into the tank body 1 through the water collecting holes 4 to absorb the water and the nutrients stored in the tank body 1. Partial water in the tank body 1 is evaporated into root ball soil through the water collecting holes 4 and is absorbed by seedling roots. When periodic drought occurs, the supply of water and nutrients for growth in the strong seedling stage can be ensured, so that the survival rate and the survival rate of newly planted seedlings are greatly improved. The iron tank body 1 is buried underground for about 2-3 years and then is oxidized and decomposed, so that the mission of storing and providing nutrition for the seedlings in the survival and strong seedling period is completed. After the tank body 1 is oxidized and decomposed, the content of the Fe in the parent material of the soil can be increased, and a containing hole can be formed in the soil for a long time, so that the water-containing capacity of the soil is increased.
