Problems solved by technology

[0004] Spinach seeds are small in size and full in granules. In the actual cultivation process, the seed skin is too thick, and the inner germ cannot grow through the skin, resulting in a low germination rate of spinach seeds. At the same time, because spinach seeds contain a small amount of bacteria or microorganisms, These microorganisms easily absorb the necessary nutrients inside the seeds during the germination process of

Embodiment 1

[0029] The experimental site was selected in July 2014 at the Zhuanghang Experimental Station of the Shanghai Academy of Agricultural Sciences

[0030] (1) Seed cleaning: the spinach seeds purchased in the market are placed in a sodium bicarbonate solution with a mass fraction of 1.5% and soaked for 24 hours. After the soaking is completed, the spinach seeds are washed repeatedly for 10 minutes, and the spinach seeds are drained and set aside;

[0031] (2) soaking: the spinach seed that step (1) obtains is put into cold water soaking seed 3 hours, and the massfraction that adds the same volume as cold water is the boric acid solution of 0.1% in described cold water;

[0032] (3) Somatotropin pretreatment: take out the seeds obtained in step (2) and soak in a plant growth regulator for 30 minutes. The plant growth regulator is: 80mg / L DA-6+120mg / L GGR6+60mg / LNAA+25mg / LIBA+40mg / LCPPU, after soaking, take out the seeds and treat them with a high-voltage electrostatic field. The ...

Embodiment 2

[0039] (1) The last batch of spinach was harvested in October 2014. After that, the field began to be cleaned, fertilized, plowed and leveled.

[0040] (2) Select 16 spinach germplasm resources to sow on October 15, plant two square meters of each resource, water once a day, and weed regularly.

[0041] (3) When the spinach is commercially available in early December, select the plants with typical characteristics of the provenance and grow vigorously for marking, and pull out the miscellaneous plants and weak seedlings.

[0042] (4) When the bolting phenomenon occurs in spinach, immediately pull out the absolute male plants and early female plants, as well as diseased and weak plants, and gradually pull out some vegetative male plants, leaving 3 to 5 male plants per square meter and The female plant serves as the seed plant.

[0043] (5) Select immature branches with stigma on the female plant, put a sulfuric acid paper bag with a length of 60 cm and a width of 30 cm, tie a ...

Abstract

The invention provides a method for high yield of spinach and reserving seeds for planting. The method includes the steps of cleaning seeds, immersing seeds, pre-treating growth hormone, accelerating germination, soil working and sowing, controlling insect diseases, managing field, selecting stock trees, bagging female plants, artificial pollination, removing bags and harvesting. The method greatly improves the disease-resistant and insect-resistant capability, lowers incidence of diseases, improves the quality of spinaches, and substantially increases high-yield capability. In this way, spinaches can be planted in summer. Excellent planting resources can be reserved, space can be saved, and a plurality of types of seeds can be reserved for planting in a same booth without interfering each other. The operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of herbaceous plant cultivation, and in particular relates to a method for high-yield and self-seed retention of spinach. Background technique [0002] Spinach (Spinacia oleracea L.), also known as Persian vegetable, red root vegetable, parrot vegetable, etc., belongs to the family Amaranthaceae and is an annual herb. It is rich in nutrition, contains more protein, multivitamins, various minerals, as well as folic acid, amino acids and dietary fiber, and has high therapeutic and medicinal value. At the same time, it is a popular vegetable in my country, which is planted in both the north and the south, and occupies a pivotal position in the daily consumption of residents and the supply of vegetables in the market. The flowers of spinach are unisexual flowers, a few have bisexual flowers, the male flowers are spikes, and the female flowers are clustered in the leaf axils. Generally, dioecious plants, a few ...
