Problems solved by technology

When many farmers grow blueberries, due to technical reasons (unreasonable park construction, unsuccessful soil improvement in the early stage, mainly because pH and organic matter are not up to standard), the growth and fruiting conditions of blueberries are poor. Difficult to get good returns
At present, many growers only know that sulfur powder and lime are needed to adjust the pH. It is difficult to grasp the specific dosage. Since the adjustment of pH takes a certain time to be effective, many growers are prone to excessive or insufficient pH adjustment. At the same time, many growers only adjust the pH in the early stage of planting, and do not pay much attention to the pH of the soil in the later stage after the pH is adjusted. When organic fertilizer is used, the corresponding organic matter will consume nitrogen when it is decomposed, and it is easy to compete with blueberries for fertilizer, resulting in poor growth of blueberries; due to improper operation methods in some parks, a large number of weeds will be produced in the field, not only competing with blueberries for fertilizer and water, but the weeding process is time-consuming It takes a lot of work, and it also affects the green cultivation of blueberries
Because blueberry is a low-fertilizer plant, some farmers only apply a small amount of nitrogen fertilizer when fertilizing. As a result, not only the growth of blueberry is affected, but its yield is also very low, and the economic benefit is not good; at the same time, there are some growers who want to increase the yield However, applying a large amount of chemical fertilizers can easily cause fertilizer damage; improper selection of fertilizers will not only result in poor fertilizer efficiency, but also easily lead to a decrease in blueberry production and even plant death; most farmers have a good understanding of the physical and chemical properties of the soil, and do not know the specific indicators of irrigation water. Be careful, unqualified irrigation water can easily deteriorate the soil that has been improved after investing a lot of resources and affect the growth of blueberries
The park can effectively improve the soil through certain methods before planting, but it is difficult to improve the soil comprehensively after planting, and even if a large amount of resources are invested, it is difficult to achieve good results

Embodiment 1

[0053] Embodiment 1 is suitable for the hilly slopes in the Jiangsu and Zhejiang provinces.

[0054] Refer to the technical plan and make adjustments according to regional characteristics.

[0055] 1 soil improvement

[0056] According to the soil test results, combined with the base fertilizer before sowing green manure, appropriately supplement mineral elements, plow the park 50cm deep, and remove weeds, gravel, branches, etc. Excavate sump to meet irrigation needs. In mid-October, green manures such as milk vetch and broad beans are planted in the park where blueberries will be planted, and 25cm of green manure is plowed in April of the second year when the green manure produces the largest fresh grass. The soil in this area is mainly weakly acidic, and sulfur is used to lower the pH. Generally, 100-200kg of sulfur is required per mu. Use mineral elements to adjust the soil organic matter content at 8-12%;

Embodiment 2

[0068] Embodiment 2 is applicable to the plain in the middle and lower reaches of the Yangtze River.

[0069] 1. Soil improvement

[0070] According to the soil test results, combined with the basal manure before sowing green manure, mineral elements are appropriately supplemented, and the park is plowed 40cm deep. From low October to early November, plant green manures such as vetch, vetch, and broad beans in the park where blueberries will be planted, and plow 20cm in April of the second year when the green manure produces the most fresh grass. The soil in this area is mainly weakly acidic to neutral, and sulfur is used to lower the PH. Generally, 120-150kg of sulfur is needed to reduce one PH per mu. Use mineral elements to adjust the soil organic matter content at 8-12%;

[0071] 2. Preparation before planting

[0072] Before planting blueberries, weeds should be removed from the farmland. After leveling the land, make a high border and dig a drainage ditch. Plow over 3...

Abstract

The invention provides a green planting method for blueberries. The method comprises the steps of (1) garden selection; (2) soil improvement; (3) preparation for planting; (4) planting; (5) water and fertilizer management; (6) disease and pest prevention and control; (7) pruning; (8) timely harvesting and overwintering protection. Compared with the prior art, the method can better improve soil in an economical manner and is a highly-efficient green cultivation method. The method can better adjust the pH of soil, enables the pH of soil to be kept at 4.3-4.8, which is most suitable for the growth of blueberries, can increase the organic matter content of soil to more than 8%, can improve the soil structure and maintain the soil moisture content, and can achieve the effects of green planting and high yield. The method effectively increases the fruit setting rate of blueberries and increases the yield.

Description

technical field [0001] The invention relates to a green blueberry planting method, which belongs to the technical field of agricultural planting. Background technique [0002] Blueberry has very high economic value, and the economic benefits of planting are very high, and it is widely cultivated in all parts of the north and south of my country. Because blueberries have high requirements on soil organic matter, PH and other indicators, the technical requirements for planting blueberries are high, and the economic investment is also large. When many farmers grow blueberries, due to technical reasons (unreasonable park construction, unsuccessful soil improvement in the early stage, mainly because pH and organic matter are not up to standard), the growth and fruiting conditions of blueberries are poor. Difficult to get the desired return. At present, many growers only know that sulfur powder and lime are needed to adjust the pH. It is difficult to grasp the specific dosage. S...
