Abstract

The present invention relates to an economic forest root-base water-saving cultivation series technique, which is an internationally unique new dry farming, high-efficiency and water-saving irrigation system which can simultaneously realize drought resisting, water retention, fertilizer application, soil improving and underground pest control. The present invention has the key points that root-covering materials with the functions of adsorption, water storage and aeration and corresponding input holes are arranged in a soil layer with the most dense plant root systems, and then, the water fertilizer and physic liquor of right amount needed by plants are poured into root-covering materials from the input holes in time according to the need of the growth and the development of plants. The increase in yield and the economic benefit of the present invention can be similar to the increase in yield and the economic benefit of trickle irrigation. Compared with the trickle irrigation, the present invention saves drought resisting water consumption by 80% and saves investment by 75% to 95%.

Description

Plant roots is irritated water-saving cultivation method

Technical field

The present invention relates to field of plant growing technology, particularly a kind of method of plant efficient water-saving culture.

Background technology

Before the present invention makes, some more advanced water-saving agricultural technology such as drip irrigation, mist filling, infiltrating irrigation etc. have been arranged.

Drip irrigation is than conventional cultivation method volume increase 20～80%, particularly melon, greengrocery, but it needs power set and Heavenly Stems and Earthly Branches hair triode road, drip irrigation to chew, and cost is very expensive, very high to water quality requirement, large tracts of land popularization under the economy that therefore is difficult in the present rural area of China and the technical conditions.

The water consumption that mist is irritated exists bigger evaporation, floats the ease loss not second to drip irrigation, and is also very high to water quality requirement, also needs to consume the more energy, and pipeline and atomizer are very expensive.

Infiltrating irrigation claims dark filling again, and the underground laying water permeating pipeline with holes that needs needs to build pond and force pump on the ground, the cost height, and the moisture content waste is many, and effect is unsatisfactory.

Summary of the invention

Purpose of the present invention just is to overcome above-mentioned existing methods defective, studies a kind of can the water saving and method effective and that cost is low.

Technical scheme of the present invention: plant roots is irritated water-saving cultivation method, and its major technique is characterised in that:

(1) in the root hair zone of plant Bao Genqu is set;

(2) place root-wrapping material in Bao Genqu, root-wrapping material is wrapped the capillary root, and root-wrapping material contains water-absorbing water-retaining agent, granular structure accelerator;

(3) Bao Genqu is provided with input hole, and the lower end of input hole contacts with the root-wrapping material of Bao Genqu, the upper end of input hole and air communication;

(4) execute in the root-wrapping material of Bao Genqu by input hole Jiang Shui, the fertile filling.

Advantage of the present invention and effect are to irrigate and improve the soil, needn't carry out on a large scale, and as long as carry out in the densely distributed root hair zone of vegetable hair radicula, low, the moisture content less wastage of cost like this, irrigation effect is good, and water, fertilizer rationally utilize, promote plant growing, remarkable in economical benefits, social benefit is better, to arid, the water-deficient area is especially suitable.

Embodiment

As shown in Figure 1, excavate the intensive part 1 of vegetable hair radicula (root hair zone) scope place part upper layer of soil, certain depth under soil layer, the degree of depth is a principle with damage root system within reason, this root hair zone is set to Bao Genqu; Put into root-wrapping material 2 at this Bao Genqu; It on it topped soil layer 3; Bao Genqu is communicated with by input hole 4 with air, and promptly an end of input hole 4 is arranged in the Bao Genqu, the other end and air communication, and input hole 4 can be with hollow tube body such as plastic sleeves such as plastics; Root-wrapping material 2 Main Ingredients and Appearances are water-absorbing water-retaining agents, granular structure accelerator, also has adhesive, bag foundation fertilizer, the cinder particle, bark fines, vinasse, rice husk, ash, peat, in the animal leftover bits and pieces particle etc. one or two or more kinds, be aided with fertilizer, agricultural chemicals etc., make it be bonded to one by adhesive, has granular structure character, with its compacting in the intensive part 1 of vegetable hair radicula, water-absorbing water-retaining agent has suctioned moisture content, topped soil layer 3 prevents its water evaporates, water-absorbing water-retaining agent constantly slowly discharges moisture content wherein in growing process, moisten the intensive part 1 of vegetable hair radicula, non-caked agglomerating when granular structure accelerator makes it humidity, and its physical characteristic has absorption, the effect that Chu Liuyu is ventilative; The pH value of adjustment root-wrapping materials 2 such as available KOH, phosphoric acid is 6～7 simultaneously.

At ordinary times, input hole 4 available object cover, but the material of ventilation preferably, as pinch with grass agglomerating with input hole 4 tubular bodies and an end plug of air communication firmly, both can prevent the water in the root-wrapping material 2, fertile drain evaporation, can suitably keep certain circulation of air again simultaneously; Need when adding water, fertilising, the water of certain proportioning, the fertile filling by input hole 4 can be executed in the root-wrapping material 2 root-wrapping material 2.

Owing to directly execute water in the intensive part 1 of vegetable hair radicula, every mu of (1/15 hectare) water consumption was no more than 2～8 cubic metres in every month, compared with other water-saving method, had improved the availability of water, and water-saving result is very obvious; Owing in root-wrapping material 2, can directly add the required fertilizer of plant growing, also improved fertilizer utilization ratio greatly, effect of increasing production is obvious, and helps soil melioration, prevents soil degradation.

The resisting drought saving water effect compares:

Method every mu of every water consumption per month in dry season (cubic meter) surface evaporation underground leakage investment (unit/mu)

This patent 2-8 lacks 150-500

Infiltrating irrigation about 20 is few many more than 1500

Drip irrigation more than 50 what more than 2500

How much mist irritates 50 or more about 2000

Annotate: the drip irrigation equipment costliness

The PF value of root-wrapping material 2 is less than 0 dynes/cm, prevents that moisture content is toward underground leakage.

For economic fruit-bearing forest, opened living generally can increasing production more than 20%, income can improve 30%; For anti-season melon dish, can increase production 30%, income can improve more than 40%.

Water-absorbing water-retaining agent in the root-wrapping material 2 can play the storage effect again for rainwater, and moisture content is too many near the unlikely root system of plant.

To be large tracts of land of the present invention be crossed as application example in the shady adult economic fruit-bearing forest at tree crown to Fig. 2.Bearing tree crown diameter 5, the bag root place 6 that embarks on journey, input hole 4.
