A method for predicting assimilate yield of greenhouse solanaceous crops

Abstract

A method for predicting assimilation product yields of greenhouse solanaceae type crops, the method comprising the following steps: 1) establishing a prediction model for simple-leaf assimilation product yields of greenhouse solanaceae type crops; 2) determining an effective leaf area of a greenhouse solanaceae type crop; and 3) substituting the obtained effective leaf area of the greenhouse solanaceae type crop and a light interception amount into the prediction model in the step 1 so as to obtain an assimilation product yield of the greenhouse solanaceae type crop. According to the method, the defects in predicting assimilation product yields of solanaceae type crops are overcome, a theoretical basis is provided for improving prediction of greenhouse solanaceae type crop yield, and a certain advancing effect is provided for improving the level of technology for greenhouse solanaceae type crop cultivation.

Description

technical field [0001] The invention belongs to the technical field of protected cultivation, and in particular relates to a method for predicting the output of assimilated products of solanaceous crops in a greenhouse. Background technique [0002] Solanaceous crops are one of the main crops cultivated in greenhouses, and the growth simulation model of greenhouse solanaceous crops plays a vital role in the cultivation and management of greenhouse crops. [0003] In the study of the growth and development simulation of solanaceous crops in the greenhouse, the yield of assimilates is an important link in the growth and development simulation model of the greenhouse. There are two methods for calculating the assimilation product yield at present. The first is to use destructive sampling to obtain the increase in dry weight of solanaceous fruits, and use this as the yield of solanaceous crops in greenhouses; the second method uses photosynthesis models, Take the output of the ...

Problems solved by technology

[0004] These two methods both have the following disadvantages: First, the first method calculates the assimilation product yield as the net assimilation product yield. After photosynthesis of leaves, the assimilation products produced are transported to various organs through transporting tissues. After each organ receives the assimilation products After sustaining respiratory consumption, the remaining assimilated products can be converted into components of various organs

The yield of assimilated products calculated by the second method is relatively high. The reason is that when the leaves of solanaceous crops in the greenhouse undergo photosynthesis, the assimilation needs to maintain respiration to maintain the life activities of the leaves, which consumes a part of the assimilated products. Therefore, the second method is adopted. The output value of the assimilated product obtained by the method is higher than the actual assimilated product
