Embodiment 1

[0025] Choose basically neutral sandy loam or garden soil, plow 30cm deep in the previous winter, open the box at 180cm, and rake the topsoil finely. Before planting, the soil was disinfected, and 2.5% 84 disinfectant was sprayed while turning the soil. Sow peanuts in mid-April, row spacing 60 cm, nest spacing 12 cm, sow 2-3 plants per nest; wait until mid-May when the flowers grow vigorously, sow Baoshan Viola seeds between the rows, and spray 0.1% to 0.2% of high manganese Moisten the seeds with the potassium acid solution, mix the seeds with fine soil, and sprinkle them between rows of peanuts for sowing. After planting Baoshan viola, when the seedlings grow the first true leaf, start to divide the seedlings. When transplanting the seedlings, stretch the root system, pour the bottom water thoroughly, and apply 150-200 kg / mu of composted and decomposed organic fertilizer. When it grows to more than 5 leaves, it can be planted; the planting density is 25-30 plants / square met...

Embodiment 2

[0027] In the winter of the previous year, the field for planting peanuts was plowed 30 cm deep, the topsoil was raked and leveled, and the soil was sterilized by sun exposure. Sow soybeans in mid-March of the following year, apply ternary compound fertilizer 40kg per mu, row spacing 70cm, nest spacing 14cm, sow 3-4 plants per nest; after sowing all seedlings, open the field drainage ditches in time to make the ditches connected and smooth drainage and irrigation , There is no water on the border of the rainfall to prevent rotten seeds. After the weather gets warmer, Viola baoshan resumes regeneration or the seeds left in the soil the previous year germinate and grow. Nitrogen topdressing at early flowering stage of soybean promotes flower development and young pod growth. Generally, 3.5-5kg of urea is sprayed on the rainy mu. If the plant grows too vigorously, the amount of urea can be reduced or not applied as appropriate. Spray fertilizer on the leaves of soybeans at the ...

Abstract

The invention discloses a viola baoshanensis interplanting method. The method comprises the following main steps of 1) preparing soil; 2) sterilizing the soil before crop planting; 3) seeding peanutsor soybeans in spring; and 4) sowing viola baoshanensis between rows or promoting the regeneration growth of previous-crop viola baoshanensi through water and fertilizer management when the crops growvigorously in summer. According to the viola baoshanensis interplanting method, the peanuts or soybeans which are sowed in spring are utilized for overshadowing; the steps of open sowing, seedling transplanting and field planting are adopted, or a manner of promoting the regeneration growth of the previous-crop viola baoshanensi through water and fertilizer management is adopted, so that the technical problem of planting viola baoshanensis through artificial seed seedling raising is broken through, and a hierarchical landscape of planting peanuts which bear yellow flowers in spring and planting viola baoshanensis which bears purple flowers in summer is provided; and by utilizing the ability, of hyper-accumulating cadmium, of the viola baoshanensis, the excessive cadmium risk of the peanuts is reduced.

Description

technical field [0001] The invention relates to the technical field of agriculture and restoration plants, in particular to a method for interplanting Baoshan Viola. Background technique [0002] Baoshan Viola, a perennial herb, originates from the Baoshan polymetallic mining area in Guiyang County, Chenzhou City, Hunan Province. It is a perennial herb of the family Violaceae. It has no aerial stems, 5-10 cm high, and the whole plant is densely covered with short hairs. Rhizome vertical, 4-8 mm thick, densely nodular, with several long taproots, white fibrous roots. Rhizomes shortened, occasionally with transverse rhizomes. Many leaves, all basal, rosette-shaped; leaf blade triangular-ovate, 2-4 cm long, 1.5-2.5 cm wide, apex acuminate, base heart-shaped, edges obtusely serrated and densely ciliated, serrated apex with dark Red glandular spots; both sides of the leaves are short hairs, densely villous along the veins. Flowers purple, with long stalks, pedicels and stems a...
