ACCOUNTING AND HARVESTING STANDARDS OF ALLIUM OCHOTENSE PROKH. IN THE CONDITIONS OF THE FAR EAST (BY THE EXAMPLE OF THE SOUTH OF KHABAROVSK REGION)

The purpose of the study is to determine the standards for accounting and harvesting of Allium ochotense in the Far East using the example of the south of the Khabarovsk Region. The collection of raw materials (stalks) of Allium ochotense was carried out in the field in May 2019 on the territory of the Korfovsky District forestry of the Khekhtsirsky forestry near the Levaya River (quarter 25, section 14). The methods of forest resource science were used – on accounting sites and projective coverage. Silvicultural and geobotanical descriptions of phytocenoses with the participation of Allium ochotense included the following elements: forest type, density, tree stand, undergrowth, undergrowth, and ground cover. A record of samples (stems) was made, in which for each site the average values of the number of stems were determined per 1 square meter (47.5 pieces), projective cover (14.5 %), average height (25 cm) and wet weight (220.9 g/m2 or 2209 kg/ha). Also, 10 prototype samples of Allium ochotense were collected, then calculated, with the determination of their average height (25.5 cm) and weight in the raw (48.0 and 4.81 g) and air-dry states (5.55 and 0.56 g), as well as the total percentage of the yield of raw materials (11.6 %). The productivity of the studied species, depending on the projective cover (from 10 to 100 %) and the degree of stem density (from 20 to 80 pieces per 1 m2) in three gradations – minimum, average and maximum, varies from 1000 to 4000 kg/ha, and the permissible collection – from 400 to 1600 kg/ha. The terms and frequency of harvesting the onion of Okhotsk are determined.
