Detection method for relieving peachtree dormancy

Abstract

The technology belongs to the field of facility fruit tree culture. When a peachtree grows to a certain stage, the peachtree enters a dormancy state, the dormancy period is a growth period of relative slow growth, the growth period needs the support of low temperature of around 7 DEG C, and in the process, forms and contents of blossom buds are subjected to extremely subtle change. When the dormancy reaches certain degree, qualitative change occurs, namely the dormancy period is relieved, if the dormancy time is overlong, the mature period is delayed, and if the dormancy time is insufficient, the germination cannot occur. Therefore, timely and accurate mastery of dormancy relieving period is a guide basis for the beginning of temperature rise of a facility fruit tree. During the forcing culture and early forcing culture of the peachtree, the accurate mastery of the dormancy period of the peachtree is a key to the early selling and successful culture, but a chilling requirement estimation method cannot meet the production requirement. The invention provides a simple, convenient, rapid, accurate and cheap method capable of indicating the dormancy relieving of the blossom buds of the peachtree.

Description

Technical field: [0001] It belongs to the field of facility fruit cultivation. technical background: [0002] In the promoted cultivation and early promoted cultivation of peach trees, accurately grasping the dormant period of peach trees is the key to early listing and successful cultivation. The dormancy time is too long to delay the maturity period, and the dormant time is insufficient to prevent germination. Therefore, it is very important to predict the dormancy period of peach trees. Over the years, scientific and technological workers have established four models for calculating the dormant period, namely the Utah model, the 0-7℃ model, the lower than 7℃ model, and the dynamic model. In recent years, the Zhengzhou Fruit Tree Research Institute and other units have estimated the dormant cold demand of peach trees for multiple varieties, but this estimated value is only a rough cold demand value, and the calculation results of each calculation model are different and vary gr...

Problems solved by technology

Although the dormancy period of the peach tree is known by this method, half a month has passed, and it is too late to be used in production; the method of estimating the cooling capacity not only requires nearly two months of temperature records and Temperature and humidity management, and with a lot of blindness
