Double-cropping cultivation technology of red-pulp guavas

Abstract

The invention discloses a double-cropping cultivation technology of red-pulp guavas. A crystal guava variety and wild purple-fruit myrtle are grafted, planting is performed by enhancing seedling management after grafting cultivation, and the planting step comprises land preparation, root treatment in mud, field planting, fertilizer and water treatment, double cropping, fertilizer application, dendrobium harvesting, pruning, management of flowers and fruits of the red-pulp guavas, truncation, germination and the like. The double-cropping technology research of fruit trees and flowers are performed by the aid of the habits that dendrobium loves shade and the red-pulp guava trees need a lot of sunlight, the benign ecological environment suitable for the red-pulp guavas and the dendrobium to grow is continuously researched and created by enhancing management in the planting process, the high yield of the red-pulp guavas and the dendrobium is realized, a herbicide for weeding and a pesticide for insect killing are not required in the planting process, the ecological and environment-friendly planting effect can be realized through double cropping, and the problems that existing red-pulp guavas have soft pulp and don't have deep enough color are further solved.

Description

【Technical Field】 [0001] The invention relates to the technical field of fruit tree planting and cultivation, in particular to a red-heart guava multiple crop cultivation technique. 【Background technique】 [0002] At present, the common guava on the market is white heart, red heart guava fruit is relatively rare, red heart guava fruit matures and the flesh is red flesh taste softer than white heart guava, and the fruit flavor is stronger than white heart guava. It is especially suitable for diabetics. It contains a lot of vitamin C and an ingredient similar to insulin, which can speed up insulin secretion and lower elevated blood sugar. In addition, red heart guava also has a certain degree of regulation on human immunity. It can inhibit the occurrence of diabetes complications. After people consume it, it can invigorate the spleen and reduce accumulation, can also astringe the intestines and relieve diarrhea, can regulate the intestines and stomach, and has a certain effect of c...

Problems solved by technology

[0003] At present, the seedlings of red guava on the market are generally introduced and planted, mainly the guava variety "Red Heart Guava" introduced from Taiwan. The guava of this variety is light red and the flesh is soft. The cultivation method adopts conventional planting methods , that is: nursery stock cultivation, site preparation and transplantation, fertilizer and water management, bagging, shaping and other steps. For example, Chinese patent CN 103733933B discloses a cultivation method of guava fruit trees. The production steps of this invention are: selecting land to build gardens, fertilizing and watering Management, bagging and shaping, the invention does not disclose how to cultivate the red guava, nor does it improve the quality of the existing red guava fruit, and in the prior art, it is seldom to use fruit trees and flowers to carry out multiple planting, because The planting environment of flowers and fruit trees is quite different, and most flowers are planted in pots and soilless. The process of planting in gardens is lengthy and the management is complicated

Therefore, need to solve following problem in carrying out red heart guava multiplanting cultivation: (1) overcome existing red heart guava fruit color light red, the problem of soft flesh (2) overcome fruit trees and flowers are not easy to replant so as to improve land utilization rate Problem; (3) improve the problem that the red heart guava fruit tree after grafting is low in the transplanting process; (4) overcome the problem of spraying pesticides and insecticides in the red heart guava plantation process
