Embodiment 1

[0023] (1) Clean up the cone impurities: spread a wet cloth on the floor, place a single layer of cones in the middle of the wet cloth, then tie the four sides of the wet cloth with a rope, then repeatedly squeeze the cones in the wet cloth, and finally open the rope to clean Leaf needles and soil debris carried by the cones;

[0024] (2) Pre-drying of cones: spread 2 layers of newspapers on the indoor floor first, then spread the cones cleaned of impurities on the newspapers, and pre-dry them for 10 hours. The indoor temperature is 24±1°C;

[0025] (3) Degreasing: pile the pre-dried cones into a pile, cover the cones with a layer of straw, pour 5% lime water every 12 hours for stack retting, and stack retting time is 48 hours;

[0026] (4) Drying: Spread the retting cones flat in a constant temperature blast drying box for drying, the temperature is controlled at 46±1°C, the blast is turned to the maximum level, the thickness of the stack is 10~12cm, and the drying time is 7...

Embodiment 3

[0035] (1) Clean up the cone impurities: spread a wet cloth on the floor, place a single layer of cones in the middle of the wet cloth, then tie the four sides of the wet cloth with a rope, then repeatedly squeeze the cones in the wet cloth, and finally open the rope to clean Leaf needles and soil debris carried by the cones;

[0036] (2) Pre-drying of cones: Spread 3 layers of newspapers on the indoor floor first, then spread the cones cleaned of impurities on the newspapers, and pre-dry them for 10 hours. The indoor temperature is 23±1°C.

[0037] (3) Degreasing: pile the pre-dried cones into a pile, cover the cones with a layer of straw, pour 6% lime water every 12 hours for stack retting, and stack retting time is 48 hours;

[0038] (4) Drying: Spread the retting cones flat in a constant temperature blast drying box for drying, the temperature is controlled at 47±1°C, the blast is turned to the maximum level, the thickness of the stack is 12~15cm, and the drying time is 6...

Abstract

The invention provides a treatment method for cones of keteleeria cyclolepis. The treatment method comprises the following steps: kneading the cones on wet cloth to clean up impurities at first, and then spreading the impurity-free cones on an indoor floor for 10 hours' pre-drying; then, covering the pre-heated cones with a layer of straw, and pouring lime water every 12-24 hours for 48 hours' stack retting; putting the cones subjected to the stack retting into a constant-temperature air dry oven at a spreading thickness of 10-15 cm for 48-72 hours' drying; in the drying process, turning over the cones every 2-4 hours; after the cones are dried and cracked, putting the cracked cones into a bamboo sieve, and gently beating the cracked cones with a wood stick till seeds completely jump out of the cracked cones; collecting and kneading the seeds to remove seed wings; and after the sieving, filling a sack with the treated seeds, and placing the sack at a ventilated place for drying. The treatment method provided by the invention is prevented from being affected by the climate; the cone cracking time is short, that is, the cones can be neatly cracked within about 5 days; the seed yield can reach up to 88.9% and the seed germination rate is 96.9-98.1%; and the efficiency of treatment of the cones of keteleeria cyclolepis and the seed quality can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of tree fruit treatment, and relates to a treatment method for cones of Chinese fir tree. Background technique [0002] Araucaria (( Keteleeria cyclolepis Flous ) belongs to the genus Keteleeria of Pinaceae (Pinaceae). It is a unique evergreen tree in my country and a national third-level protected plant. It is now scattered in Guangxi, Yunnan, Guizhou, Guangdong, Hunan, Fujian, Zhejiang, Jiangxi, etc. Hills and low mountains below 1000m above sea level in provinces and regions. The trunk is tall and straight, the material is fine, the material color is beautiful, and the branches and leaves are luxuriant. It is an ideal tree species for mountain afforestation, timber forest and landscaping. Due to comprehensive factors such as man-made felling, its own biological characteristics and natural environment, the natural germplasm resources of Yale fir chinensis have been seriously lost and are now in an endange...
