Predication method of forcing culture heating period of greenhouse citrus

Abstract

The invention discloses a predication method of a forcing culture heating period of a greenhouse citrus. The predication method of the forcing culture heating period of the greenhouse citrus comprisesthe following steps of collecting a scion after summer shoots bear fruits and mother shoots turn green and are aged so as to prepare a stem sample; weighing the stem sample, and leaching the stem sample in nitrate nitrogen to prepare a leaching solution; detecting the concentration of the nitrate nitrogen in the leaching solution to detect the content of the nitrate nitrogen in the stem sample; and repeating the three steps, and starting to heat a forcing-cultured citrus until the detected value of the content of the nitrate nitrogen in the stem sample is continuously less than a set value for 2-3 times. The predication method of the forcing culture heating period of the greenhouse citrus, disclosed by the invention, has the advantages that the time needed by predicating fruit bearing mother shoot flower bud differentiation quality can be obviously shortened, the optimal heating period of the forcing-cultured citrus is obtained; in addition, by using a test paper to detect the concentration of the nitrate nitrogen, the predication method is convenient and fast to use and is simple and practical; and the predication method is easy to master and apply by citrus growers.

Description

technical field [0001] The invention relates to the field of enhanced cultivation in greenhouses, in particular to a method for predicting the warming period of enhanced cultivation of citrus in greenhouses. Background technique [0002] Flower bud differentiation is the process of transition from vegetative growth to reproductive growth of fruit tree branches, flower bud induction and floral organ differentiation, which has an important direct impact on the flower quantity, flower quality and fruit setting rate of the tree in the next year. The cultivation of citrus in the greenhouse can break the dormancy of the citrus tree early. When the flower bud differentiation of the tree is fully completed, the earlier the heating time is, the earlier the fruit will be on the market, and the higher economic benefits can be generated; therefore, it is determined to promote the cultivation of citrus. The optimal heating time is related to the flowering quantity and flowering quality o...

Problems solved by technology

However, this method generally takes more than 10 days from obtaining the fruiting mother branch, and then through water insertion culture, to the branch flower buds that can be observed with the naked eye; Relative humidity must be kept above 90% in ambient conditions

On the one hand, this environmental condition is very easy to breed mold and cause branch corruption, which has a great impact on the accurate statistics of the budding rate of the mother branch; on the other hand, the unstable or unsatisfactory temperature and humidity will cause the branches to not germinate or the germination time will be greatly delayed. , which seriously affects the fast and accurate statistical branch budding rate, making it easy for citrus growers to miss the best time to promote the cultivation of citrus
