A kind of irrigation method of loquat tree

Abstract

The invention discloses an irrigation method of loquat trees and belongs to the field of fruit tree irrigation. The loquat trees in south subtropical south China are subjected to drip irrigation fromlate September to January of the following year with the drip irrigation amount of 35-60kg of water each loquat tree once every 6-10 days for a drip cycle. The irrigation method is easy to implement and accurate in index, time for drip irrigation can be judged by dividing the target irrigation amount into the number of drippers and the flow rate of the drippers, and convenience is brought to farmers to well implement the scheme; compared with the prior art, the irrigation method has the advantages of less amount of water involved, high operability and capabilities of saving water and labor andresisting soil drought hazard in loquat flowering and fruit bearing periods.

Description

technical field [0001] The invention belongs to the field of fruit tree irrigation, in particular to a loquat irrigation method. Background technique [0002] Soil drought is an agrometeorological phenomenon in which there is no or little rain for a long time, resulting in insufficient soil moisture, and the plant roots cannot absorb enough water to compensate for the consumption of transpiration, which destroys the water balance of crops and reduces production. The degree of damage to crops caused by soil drought is related to the season of occurrence, the type, variety, and growth period of the crops. Beibu Gulf), most of which occur in autumn and winter, during which loquats are in the flowering and fruit setting period, and the water demand happens to be the peak of the year. [0003] Usually, in the subtropical South China loquat cultivation area, the average monthly rainfall from March to September is more than 100 mm, which can meet the needs of loquat branch and lea...

Problems solved by technology

The first is the furrow irrigation method. In loquat orchards where irrigation is convenient, the natural drop is used to set up irrigation ditches by excavating water to the rhizosphere of loquats. This method has good irrigation effects, but due to natural conditions, it is not suitable for generalization.

The second is the pipeline irrigation method. In loquat orchards with water sources nearby, water is sent into the irrigation park through power and pipelines. A water outlet is set at a certain distance, and each outlet is connected with a hose with a diameter of 20 mm. Manual mobile irrigation, this method of irrigation has a certain effect, but it is difficult to irrigate quantitatively, and it is labor-intensive

The third is the sprinkler irrigation method, which sends water from the water source area into the irrigation park through power and pipelines, and installs a nozzle at a certain distance. This method of irrigation has a better effect, but it is limited by the requirements of sufficient water source and sufficient power, so it is difficult to popularize

In practice, farmers are generally unable to measure the water content of the soil, so the conclusions of the above articles can only guide farmers to use sprinkler irrigation methods, and the specific sprinkler irrigation frequency and irrigation volume can only be based on experience.

[0011] That is to say, the researches on the above-mentioned prior art are all carried out under the general irrigation standard as the index, and have not combined with local conditions to propose operable irrigation index according to local conditions

In addition, if some of the irrigation standards mentioned above are converted into the irrigation volume of each loquat tree or the annual irrigation volume of loquats, the water consumption is still very large
