Planting method capable of improving pearl guava quality

Abstract

A planting method capable of improving pearl guava quality and includes plant ridging, planting, shaping, water management, fertilizing management and flower-fruit management. The water management and fertilizing management method uses soluble fertilizers for each plant each year, the soluble fertilizers include 1150-2750g urea, 790-1290g potassium nitrate, 160-1120g monoammonium phosphate, 80-170g amino acid, 0-200g calcium nitrate, 0-70g zinc sulfate, 0-70g borax and 0-130g magnesium sulfate, and the soluble fertilizers are mixed with water of a required irrigation amount, and the mixture is applied to the soil for pearl guava trees through pipelines. The planting method sufficiently utilizes a water-fertilizer drip irrigation system, trace element fertilizers and organic fertilizers such as amino acid, calcium, magnesium, zinc, borax and the like are added according to habitual nutritional needs of different growth phonological phases of pearl guava, and accordingly, quality decline and instability of pearl guava due to seasonal drought and nutritional unbalance in Lingnan areas are reduced, and the planting method is high in practicality and has good popularization prospect.

Description

technical field [0001] The present invention relates to the improvement of the planting method of pearl guava. Background technique [0002] Pearl guava has a history of more than 20 years since it was introduced to the coast of South China for production. Guava is a plant of the genus Guava in the Myrtle family, commonly known as plucked fruit and chicken arrow fruit. It has a long history of cultivation in southern my country and is widely planted. Traditional guava varieties generally bear fruit 1-2 times a year, but the pearl guava that is now introduced and cultivated can bloom and bear fruit all year round as long as the temperature is right. At present, Lingnan area is an important production base of guava in mainland my country. Due to its rich nutrition, wide application and good economic benefits, the planting industry of guava has developed rapidly in recent years, and the planting scale has continued to expand. It has become an important source of income for loc...

Problems solved by technology

However, although most areas in south of the Five Ridges are humid and rainy all the year round, seasonal drought still directly affects the absorption of nutrients by guava, which has a serious impact on the stability of guava quality, and there are large differences in the quality of fruits harvested in different seasons; in addition Due to the traditional guava cultivation method, partial application of nitrogen and phosphorus fertilizers, the ratio of nutritional requirements for pearl guava fruit is unreasonable, and the amount of other element fertilizers and organic fertilizers is too small, resulting in a considerable part of the poor quality of the fruit and low economic benefits.
