Treatment method for quickening germination of carya illinoensisthin-shell hickory-nut seed

Abstract

The invention mainly relates to the technical field of the plantation of fruit trees, and discloses a treatment method for quickening the germination of a carya illinoensisthin-shell hickory-nut seed. The treatment method comprises the following steps of seed soaking, seed drying, seed fermentation, seed pregermination and seed sowing. The method is simple; the batch operation can be carried out; the pregermination time of the carya illinoensisthin-shell hickory-nut seed is shortened to be 12 to 13 days; after the sowing, the germination rate reaches 94.7 percent; the plantation efficiency is obviously improved; the economic income is increased by 9.6 percent; the picked carya illinoensisthin-shell hickory-nut seed together with pericarp is put into an acetic acid solution to carry out thefor soaking; a pH (potential of Hydrogen) value is lowered; the dormancy of the seed is slowly broken; after being soaked, the seed is subjected to freeze drying, and can be stored at a normal temperature; the storage and transportation costs are savedreduced; the water content of the seed can be quickly decreased; the loss of a nutritional ingredient in the seed in a sun-drying process is avoided; the vigor of an embryo is maintained; apertures of the pericarp are increased; the oxygen is quickened to enter the seed; the breakage of the dormancy of the seed is facilitated; the vigor of the embryo is improved; the germination rate of the seed is improved; the germination time is shortened.

Description

technical field [0001] The invention mainly relates to the technical field of fruit tree planting, in particular to a treatment method for accelerating the germination of pecan seeds with thin shells. Background technique [0002] Thin-shelled hickory, just called American hickory, is a very good urban and rural greening tree species and fruit tree species. The kernel is edible, and the delicious oil is squeezed for consumption. The material is tough. More than 70%; hickory nuts contain high nutritional content, rich in protein, amino acids, unsaturated fatty acids, vitamins and mineral elements, can nourish brain cells, enhance brain function, prevent arteriosclerosis, protect the liver, regulate blood sugar, beauty and hair care , relieve fatigue, more and more consumers love. [0003] At present, pecans with thin shells mostly use grafting to raise seedlings, but when cultivating new varieties, seedlings need to be cultivated. When cultivating seedlings with seeds, they ...

Problems solved by technology

[0003] At present, pecans with thin shells mostly use grafting to raise seedlings, but when cultivating new varieties, seedlings need to be cultivated. When cultivating seedlings with seeds, they need to undergo sand storage and germination treatment. The treatment time is about 90 days, and 30 to 40 days after sowing Only when the seeds are unearthed and germinated, the germination rate of the seeds can only reach about 80%, which obviously reduces the planting efficiency of the pecans
