Problems solved by technology

At present, there have been a few related reports on seedling breeding technology of Sapindus sativa seedlings. Most of the germination methods such as wet sand layering, sulfuric acid soaking, and laser minimally invasive methods are used for seed treatment. The technical links are complicated, and it is difficult to popularize and utilize them in large-scale field breeding. , and most of the fruits are directly soaked in water after picking, retting, and scrubbing, which is not only time-consuming and laborious, but also a great waste of the pulp rich in active ingredients of saponins

Embodiment 1

[0014] In mid-October, choose robust Sapindus plants to collect fruits. After the fruit is picked, it is placed in an electric blast drying oven, and the temperature is set at 35°C to reduce the water content of the pulp to 8%. After the pulp and seeds are separated, they are taken out and packed in mesh bags, and stored in a ventilated and dry warehouse. 20°C. In the spring of the following year, choose a field with loose and fertile soil and convenient drainage and irrigation as a nursery, remove weeds, and apply 3000 kg of decomposed organic fertilizer containing 15% of the quality of medicinal residues per mu (wherein the medicinal residues are composed of black herb residues, sealwort residues, wolfberry medicinal residues, etc.) Dregs, mulberry leaf dregs and licorice dregs are mixed according to the weight ratio of 3:2:3:4:1), and then plowed and leveled to build a seedbed with a height of 25cm and a width of 100cm, and dig drainage ditches and aisles. Before sowing in...

Embodiment 2

[0016] In mid-October, choose robust Sapindus plants to collect fruits. After the fruit is picked, it is placed in an electric blast drying oven, and the temperature is set at 30°C to reduce the water content of the pulp to 5%. After the pulp and seeds are separated, they are taken out and packed in mesh bags, and stored in a ventilated and dry warehouse. 25°C. In the spring of the following year, choose a field with loose and fertile soil and convenient drainage and irrigation as a nursery, remove weeds, and apply 2000 kg of decomposed organic fertilizer containing 15% of the quality of medicinal residue per mu (wherein the medicinal residue is composed of black herb residue, sealwort residue, wolfberry medicinal residue, etc.) Dregs, mulberry leaf dregs and licorice dregs are mixed according to the weight ratio of 1:2:2:1:2), and then plowed and leveled to build a seedbed with a height of 20cm and a width of 90cm, and dig drainage ditches and aisles. Before sowing in the sp...

Embodiment 3

[0018] In mid-October, choose robust Sapindus plants to collect fruits. After the fruit is picked, it is placed in an electric blast drying oven, and the temperature is set at 25°C to reduce the water content of the pulp to 10%. 25°C. In the spring of the following year, choose a field with loose and fertile soil and convenient drainage and irrigation as a nursery, remove weeds, and apply 4000 kg of decomposed organic fertilizer containing 15% of the quality of medicinal residue per mu (wherein the medicinal residue is composed of black herb residue, sealwort residue, wolfberry medicinal residue, etc.) Dregs, mulberry leaf dregs and licorice dregs are mixed according to the weight ratio of 5:3:4:5:3), then plowed and leveled, a seedbed with a height of 35cm and a width of 120cm is built, and drainage ditches and passages are dug. Before sowing in the spring of the next year, take out the stored fruit, peel the seeds for water selection, and remove the seeds that are not plump...

Abstract

The invention discloses a seed field seedling growing method for sapindus mukorossi gaertn, and belongs to the technical field of plant seedling growing. The seed field seedling growing method includes the steps of fruit collecting and storing; seedbed preparing; seed processing; sowing; post-sowing managing. According to the seed field seedling growing method, after mature fruits of the sapindus mukorossi gaertn are collected, the water content of pulp of the fruits is reduced, the fruits are dried and stored in a ventilation mode, seeds are obtained in a peeled mode before sowing is carried out and sequentially soaked with water and a spermidine solution, then sowing is carried out in a field where decoction-dreg contained decomposed manure is applied, multiple complex technical links for seed bud forcing treatment are avoided, after the seeds are sown, the sprouting speed is high, grown seedlings are orderly, plant root systems are well developed, and the grown seedlings are robust. The fruits stored with the technology are easily peeled mechanically, the seed peeling efficiency is improved, the peeled pulp can be directly used for production and processing such as saponin extracting, and the use value of the fruits of the sapindus mukorossi gaertn is increased. The seed field seedling growing method is of great significance in improving the production efficiency and saving cost when large-scale field seedling growing of the sapindus mukorossi gaertn is carried out.

Description

technical field [0001] The invention belongs to the technical field of plant seedling cultivation, and in particular relates to a method for raising seedlings of Sapindus seeds in a field. Background technique [0002] Soapzi ( Sapindus mukorossi Gaertn.) is a deciduous tree species of Sapindaceae Sapindaceae. It is mainly distributed in the south of the Huaihe River Basin in my country. It grows fast, bears fruit early, and has strong resistance. It has wide requirements on climate and soil environment. It is a common ecological greening and autumn color The landscape tree species is recommended by the Forestry Department of Zhejiang Province as one of the top ten plain greening tree species; its seed kernel oil content reaches 42%, and the peel saponin content reaches 10.8%. It is also an important biomass energy and bio-detergent raw material tree species in my country. In order to standardize the cultivation and utilization activities of Sapindus raw material forests, i...
