Embodiment 1-10

[0023] Embodiment 1-10, concrete steps are as follows:

[0024] (1) Selection of seedlings: Select 1-year-old potted seedlings of hickory nuts cultivated in the nursery stock base of the Department of Landscape and Horticulture of Jiangsu Vocational College of Agriculture and Animal Husbandry Science and Technology. One plant per pot. The seedlings are basically the same size, with an average seedling height of 25 cm and an average ground diameter of 4.5 mm. The size of the pot is: 30cm×30cm (upper edge diameter×height), each pot contains about 10Kg of soil, and each pot is numbered. The texture of the basin soil is sandy loam, and the basic nutrients are consistent. For details, see figure 1 ;

[0025] (2) Fertilizer weighing: according to figure 2 Medium N, P, K fertilization level table Weigh urea, superphosphate and potassium chloride, control the amount of nitrogen (N) to 1-3g / plant, and the amount of phosphorus (P 2 o 5 ) is 0.5-1.5g / plant, potassium application ra...

Abstract

The invention discloses a fertilizing method for facilitating growth of carya illinoensis seedlings, and belongs to the technical field of plant seedling fertilization. The fertilizing method includes the steps of seedling selecting, fertilizer weighing, fertilizer treating and fertilizer applying. By controlling amounts of urea, calcium superphosphate and potassium chloride during fertilizing, a nitrogen application rate (calculated by pure N (nitrogen)) is ensured to be 1-3 grams per plant, a phosphorus application rate (calculated by P2O5 (phosphorus pentoxide)) is ensured to be 0.5-1.5 grams per plant, a potassium application rate (calculated by KO2 (potassium superoxide)) is ensured to be 0.5-1.5 grams per plan, and the highest growth rate is ensured under the circumstance of applying the minimum amount of fertilizer. The fertilizing method has the advantages that mixture ratio of the fertilizer is controlled precisely, utilization rate of the fertilizer is guaranteed, and planting cost is saved.

Description

technical field [0001] The invention relates to the technical field of plant seedling fertilization, in particular to a fertilization method for promoting the growth of pecan seedlings. Background technique [0002] Thin-shelled hickory is a deciduous tree of the Juglandaceae Hickory, also known as long hickory and American hickory. The place of origin is the United States or Mexico. It integrates multiple values ​​of fruit, wood and greening. It is introduced as a multi-purpose tree species in my country. Predecessors have done some research on techniques such as the introduction of thin-shell hickory varieties and high-yield cultivation, but the results are not consistent. Nitrogen, phosphorus, and potassium are the three major elements of fertilizers necessary for the growth of fruit trees, and play an important role in the growth and development of fruit trees. There are few research reports on walnut fertilization technology in the predecessors, and the cultivation of...
