Embodiment 1
[0084] The test site is a young orchard, the planted fruit tree is apple, the variety is red Fuji, the tree is 1 year old, sowed on September 20, 2014, and the amount of sweet potato seed is 30kg / hm 2 , the amount of wild soybean seeds used is 15kg / hm 2 , the row spacing is 40cm, the sowing depth is 2cm, and a 0.5m clearing area is reserved; the amount of diammonium phosphate is 280kg / hm 2 , Sow 8cm deep. On April 12, 2015, October 17, 2015, and May 4, 2016, 5 random soil samples, 0cm-40cm in size, were taken at random, and soil soluble salts, organic matter, alkaline nitrogen, and available phosphorus were measured after mixing. , available potassium and other contents, the determination method refers to "NY / T 1121 Soil Testing".
Embodiment 2
[0086] The test site is an mature orchard, the planted fruit tree is apple, the variety is red Fuji, the tree is 4 years old, sowed on September 20, 2014, and the amount of sweet potato seed is 67.5kg / hm 2 , the amount of wild soybean seeds used is 22.5kg / hm 2 , the row spacing is 60cm, the sowing depth is 2cm, and a 1m clearing area is reserved; the amount of diammonium phosphate is 350kg / hm 2 , Sow 8cm deep. On April 12, 2015, October 17, 2015, and May 4, 2016, 5 random soil samples, 0cm-40cm in size, were taken at random, and soil soluble salts, organic matter, alkaline nitrogen, and available phosphorus were measured after mixing. , available potassium and other contents, the determination method refers to "NY / T 1121 Soil Testing". On October 8, 2015, 5 fruit trees were randomly selected to measure the average single fruit weight.

Abstract
The invention discloses an orchard simplified grassing and covering method comprising the following steps: mixed sowing Vicia villosa Roth and wild soybeans between lines in an orchard, one time fertilization, whole orchard alternative grassing and covering, and updating and multiple cropping; the invention also provides a matching mixed cropping fine-seeding fertilizer applicator comprising a frame and at least one fertilization sowing assembly; the Vicia villosa Roth and wild soybean growth periods are complementary, grow in a sprawl manner, are shallow in root system, strong in biological nitrogen fixation capability, small in water consumption, less in inspect and disease, shade tolerant and tread tolerant, thus simplifying orchard whole year alternative grassing and covering, improving production efficiency and planting benefits; Vicia villosa Roth and wild soybean mixed cropping mechanization sowing and fertilization are hard in the prior art, the mixed cropping fine-seeding fertilizer applicator can solve said problems, can realize mixed sowing, and fertilization mechanization and integration.
Description
technical field [0001] The invention relates to the technical field of green manure and forage crop production, in particular to a light and simplified method for growing grass and covering grass in an orchard based on mixed sowing of sweet potatoes and wild soybeans, and also relates to a precision sowing and fertilizing machine matched with the method. Background technique [0002] At present, most of the orchard management systems in my country follow the traditional clear tillage system, which requires deep digging of tree trays after the leaves of fruit trees fall in early winter every year, or re-planing in spring before fruit trees germinate. Throughout the growing season of the tree body, it is necessary to shovel and hoe the tree tray many times to shovel and hoe the weeds under the tree. The main disadvantages are: one is to destroy the soil structure, the surface soil temperature varies greatly, and the soil erosion is serious; the other is that the topsoil layer i...
