Rapid propagation method of ecological light matrix walnut container seedlings

Abstract

The invention discloses a rapid propagation method of ecological light matrix walnut container seedlings. The rapid propagation method of the ecological light matrix walnut container seedlings comprises the steps of harvesting and preprocessing seeds, processing and cultivating a stock seed bed, preserving heat for overwintering and soil-detached grafting; preparing a container nursery matrix, installing a nutrition pot, reducing the temperature for over-summering, additionally applying fertilizers to nursery stocks and performing transplanting from the seedling nursery and transportation. By means of the seedling raising technique, the seedling emerging speed is high, and healthy and strong grafted seedlings which can be transplanted from the seedling nursery to a large field can be cultivated only by taking 17 months from seed harvesting to the transplanting from the seedling nursery. By adopting the nursery matrix, a fermented organic fertilizer and an inorganic fertilizer are combined, the nitrogen, phosphorus and potassium demands in the growing process of walnut trees are met, the fertility is durable, the nutrition is sufficient, and grown walnut tree seedlings are good in quality. The degradable nutrition pot is adopted, transplanting with nutrient soil is achieved, root systems are not damaged during transplanting, the transplanted seedlings grow directly, and the survival rate can be larger than 98%. The nutrition pot matrix is light, transportation in mountainous areas is facilitated, and the degradable nutrition pot does not cause environmental pollution. In the rapid propagation method, a greenhouse facility is adopted, high-density and intensive propagation is achieved, seedling cultivation land is remarkably saved, and the benefit is good.

Description

technical field [0001] The invention relates to the field of cultivation technology, in particular to a method for rapid propagation of walnut container seedlings with an ecological light substrate. Background technique [0002] As the nutritional value of walnut kernels is more and more popular among people, the area of ​​planting walnut trees is also increasing. Chongqing and the Three Gorges reservoir area have now developed more than 2 million mu of walnut trees. In this way, the demand for walnut seedlings becomes larger. Traditional walnut gardening is basically seedling construction, resulting in late results, low yields, and uneven fruit quality in most orchards, which affects the economic benefits of walnut growers. Therefore, cultivating both high-quality and low-cost improved walnut rootstocks and walnut seedlings thereof is a key technology. Contents of the invention [0003] In view of the existing problems, the object of the present invention is to provide a...
