Post-Harvest De-Greening and Rinsing Methods for Walnuts
1. De-greening treatment. According to measurements, freshly harvested walnut green husks have a moisture content of 40%-45%, and the kernels have a moisture content of 20%-25%. Such high moisture content makes walnuts prone to rotting and deterioration after harvest. Therefore, after harvesting, walnuts should promptly undergo de-greening treatment.

How to Determine the Harvest Time of Walnuts? A Detailed Guide to Harvesting Methods
Timely harvesting of walnuts is very important. If harvested too early, the green husk is difficult to peel off, the kernel is not plump, the yield decreases, the kernel yield rate is low, the oil yield rate during processing also decreases, and the nuts are not resistant to storage. According to measurements, harvesting 1 day early on average reduces the dry fruit weight by 0.49%, and the kernel weight by

What are the conditions and methods for storing walnuts?
Compared with fruits, the physiological metabolism and compositional changes of walnut kernels are relatively stable, which gives walnuts a relatively long storage life. However, when walnuts are not sold or processed immediately, suitable storage conditions must be provided for them, and reasonable

Occurrence Characteristics and Control Methods of Walnut Canker
1. Distribution and occurrence characteristics. It is distributed in most walnut-producing areas. The pathogen mainly overwinters as mycelium within the diseased tissue of the current year. In April of the following year, when the temperature rises to 11.4-15.3°C, it begins to become active. In late May, conidia are formed in large numbers and spread by wind, rain, and other means, mostly invading through wounds

What are the common methods of walnut grafting?
There are many methods of walnut grafting. According to the grafting time and the type of scion, they can be divided into two categories: branch grafting and bud grafting. A grafting method that uses a section of a shoot with buds as the scion is called branch grafting, while one that uses only a single bud piece as the scion is called bud grafting. Common branch grafting methods include cleft
