Problems solved by technology

[0004] At present, the national wolfberry planting area is increasing year by year. Most wolfberry planting enterprises and growers use excessive chemical fertilizers and pesticides in pursuit of higher economic returns. This cultivation mode has caused land fertility decline, soil salinization, plant diseases and insect pests A series of problems have occurred, such as frequent yellowing and drying of wolfberry leaves, small fruit particles, and short duration of fruit picking.
At the same time, it caused a lot of waste of fertilizer resources, exacerbated the pollution of groundwater and agricultural non-point sources, as well as the decline in yield and quality of wolfberry, thereby accelerating the degradation of the environment of regional wolfberry production areas.
Therefore, it is considered to improve the traditional cultivation method of wolfberry and try to adopt interplanting schemes, but there are few studies on the interplanting of alfalfa in wolfberry orchards, and no perfect cultivation method of wolfberry interplanting alfalfa has been formed.

Embodiment 1

[0030] The cultivation technique of wolfberry interplanting alfalfa of the present invention is as follows:

[0031] (1) Lycium barbarum selection: The wolfberry varieties are high-quality, strong stress resistance, wide adaptability, and economical wolfberry varieties. The age of wolfberry trees is three years or more, the distance between the rows of wolfberry trees is between 1.0 and 1.3 meters, and the distance between rows of wolfberries is between 2.2 and 2.8 meters, so as to ensure convenient management of field farming activities, and at the same time reserve open space for the growth of alfalfa.

[0032] (2) Field management of wolfberry:

[0033] Fertilization: Use conventional fertilization techniques and conventional field management.

[0034] Apply basal fertilizer, before winter watering from late October to early November, or after thawing in spring, apply 3000kg of high-quality decomposed farmyard manure per mu for adult trees. Topdressing 30kg of urea and 15...

Embodiment 2

[0058] The present embodiment adopts the cultivation mode of interplanting alfalfa with the same embodiment 1, the difference lies in the overturning mode of alfalfa. The overturning mode of this embodiment is as follows:

[0059] Overturning: During the ripening period of summer fruit, the alfalfa is mowed, leaving a pile of 5cm, and the harvested alfalfa is smashed with a rotary tiller, part (about two-thirds) is used as green manure overturning, and the remaining part (about 1 / 3rd) Cover the harvested alfalfa with a rotary cultivator between the Lycium barbarum plants and crush it to the man-made fertilization work zone. When the next crop grows, in the mature period of autumn fruit (such as Image 6 Shown), the alfalfa is cut again, part (about two-thirds) is crushed and pressed to the fertilization belt, and the remaining part (one-third) is covered between the rows of wolfberry.

[0060] The overturning method adopted in this embodiment only needs to mow the alfalfa tw...

Abstract

The invention discloses a cultivation method for interplanting fructus lycii and medicago sativa. The cultivation method for interplanting the fructus lycii and the medicago sativa comprises the steps that the medicago sativa is interplanted among fructus lycii rows for field planting, the medicago sativa is cut for 2-5 times every year, the harvested medicago sativa is smashed, turned and pressed into green manure for field application, the medicago sativa is cut for the last time in a third interplanting year, roots of the medicago sativa is broken, turned and pressed, and the medicago sativa is interplanted again in the next year. According to the cultivation method for interplanting the fructus lycii and the medicago sativa, the fructus lycii and the medicago sativa are interplanted, so that the soil nutrient is improved, the soil fertility is improved, the use amount of chemical fertilizer is reduced, and meanwhile, the yield and quality of the fructus lycii are effectively improved.

Description

technical field [0001] The invention relates to the field of agriculture and forestry cultivation, in particular to a cultivation technique suitable for interplanting wolfberry in Northwest China. Background technique [0002] The wolfberry industry is a characteristic and advantageous industry in Northwest my country. Its output, sales volume and export volume all rank first in the world. Ningxia, Qinghai, Gansu, Xinjiang, Inner Mongolia and other regions have the largest planting area, forming an industrial layout with the core area of ​​Zhongning wolfberry, the radiation area of ​​Ningxia wolfberry, and the driving area of ​​wolfberry in Qinghai, Gansu, and Inner Mongolia. In recent years, wolfberry has been affected by climate, soil fertility decline and other issues, and its yield and quality have declined year by year. In order to solve the ecological environment in the main producing areas of wolfberry, improving land productivity is one of the problems that need to ...
