Embodiment 1

[0028] A method for cultivating large citrus seedlings, comprising the following steps:

[0029] S1. Land selection and ridge building: select windward and sunny slopes, the altitude should be lower than 700M, turn over the slopes, remove gravel and weeds, obtain citrus seedlings, and build ridges around the citrus seedlings. The section of the ridge is Trapezoidal, the soil ridge is compacted, the height of the ridge is 20cm, and the slope of the ridge is greater than 40°;

[0030] S2. Digging pits and cultivating fertilizer: Dig the citrus seedlings one month before planting. The depth of the pits is 12cm. The distance between adjacent pits is equal and the distance between the pits is 25cm. And mix it with crushed straw and corn cob, and pile it up near the citrus seedlings after mixing. The ratio of straw and corn cob is 1:2, and the application amount of straw and corn cob is 100g / hole;

[0031] S3. Transplanting seedlings: select high-quality citrus rootstock seedlings,...

Embodiment 2

[0036] A method for cultivating large citrus seedlings, comprising the following steps:

[0037] S1. Land selection and ridge building: select windward and sunny slopes, the altitude should be lower than 700M, turn over the slopes, remove gravel and weeds, obtain citrus seedlings, and build ridges around the citrus seedlings. The section of the ridge is Trapezoidal, the soil ridge is compacted, the height of the ridge is 25m, and the slope of the ridge is greater than 40°;

[0038] S2. Digging pits and cultivating fertilizers: digging pits for citrus seedlings 1.5 months before planting. The depth of the pits is 15m. The distance between adjacent pits is equal and the distance between pits is 25cm. And mix with crushed straw and corn cob, and pile up near the citrus seedlings after mixing. The proportion of straw and corn cob is 1:2, and the application amount of straw and corn cob is 125g / hole;

Abstract

The invention discloses a big citrus seedling cultivation method, and relates to the field of citrus cultivation. The big citrus seedling cultivation method comprises the six steps of land selection and ridge building, pit digging and fertilization, seedling transplanting, fertilization and irrigation, film covering protection and nursing forming. According to the big citrus seedling cultivation method, the periphery of the whole citrus rootstock seedling in the citrus seedling field is covered with the transparent film one week before the winter solstice, and the top of the whole citrus rootstock seedling is covered with the transparent film, so that on one hand, the heat preservation and protection effects can be achieved, the damage of winter wind damage to the citrus rootstock seedling is reduced, the citrus seedling can be cultivated in seasons or regions with low air temperature, the application scene and range of the method are widened, citrus popularization is facilitated, on the other hand, dew in the morning can be collected, the dew is used for irrigating the citrus rootstock seedling, water consumption is further reduced, practicability and economic benefits are improved, therefore, the method is scientific, efficient and simple and easy to operate, and popularization and use are facilitated.

Description

technical field [0001] The invention relates to the technical field of citrus cultivation, in particular to a method for cultivating large citrus seedlings. Background technique [0002] Citrus likes warmth and humidity, and is afraid of cold and dry. The annual average temperature in the area suitable for citrus cultivation needs to be 15-22 degrees, and the average temperature in cold months (January-February) is above 3 degrees. For the annual average temperature, the annual accumulated temperature greater than or equal to 10 degrees, the average temperature of cold months and the frequency of extreme low temperatures should also be considered. [0003] Therefore, when cultivating citrus seedlings, people often choose spring, the temperature rises, and the rainy season comes. Generally, the survival rate of planting citrus is relatively high. The situation is not as good as planting seedlings in autumn. [0004] At present, most of the cultivation methods are only suita...
