本项研究历经7年,对大扁杏密植栽培和栽植密度与生长、生物产量、经济产量的关系进行较系统的研究。研究结果表明,在气候和土壤条件较差的辽西干旱地区,采用密植栽培大扁杏,是实现早期丰产和显著提高经济效益的有效途径。密植栽培第4年平均亩产杏仁36.67kg,最高达65.67kg;第7年平均亩产杏仁65.97kg,最高达110.64kg。每亩栽植111～666株,定植后4～7年,每亩年利润达730～899元。
This study lasted for seven years and conducted a systematic study on the relationship between density and growth, biomass yield and economic yield of Daphnia magna. The results show that in arid areas of western Liaoning, where the climate and soil conditions are poor, the cultivation of Daphniphyllum apricot with close planting is an effective way to realize the early high yield and significantly improve the economic efficiency. In the fourth year of close planting, the average mu yield of almonds is 36.67kg, up to 65.67kg. The average annual yield of almonds in the seventh year is 65.97kg, up to 110.64kg. 111 ~ 666 plants per mu, 4 ~ 7 years after planting, annual profit of 730 ~ 899 yuan per mu.
