Embodiment 1

[0025] (1) Seed selection

[0026] Harvest the mature fruit of snow gall in November, and peel off the plump dark brown seeds for later use.

[0027] (2) Seed treatment and storage

[0028] Mix the seeds and cleaned wet river sand according to the volume ratio of seeds and cleaned wet river sand at a ratio of 1:3, put them into gauze bags and store them in the refrigerator. The temperature of the refrigerator is 1-6°C. The wet river sand contains The amount of water is kept at 10-13% mass fraction.

[0029] (3) Seed pre-sowing treatment

[0030] Before sowing, take out the gauze bag from the refrigerator, rub the seed skin with river sand in the gauze bag, rub the seed skin with river sand until the seed skin is scratched, and after rubbing the seed skin, put the gauze bag containing the seeds and river sand on the Place it indoors at 15°C to 18°C ​​for 1 day, and then put it in an artificial climate box to accelerate germination for 8 days. The temperature of the artificia...

Embodiment 2

[0040] Embodiment 2 Except that the operation of the following steps is different, all the other steps are the same as in Embodiment 1.

[0041] (2) Seed treatment and preservation

[0042] The volume ratio of seeds to cleaned wet river sand is 1:5.

[0043] (3) Seed pre-sowing treatment

[0044] The gauze bags filled with seeds and river sand are placed indoors at 15°C to 18°C ​​for 2 days, and then placed in an artificial climate box to accelerate germination for 12 days. The temperature of the artificial climate box is 20°C±1°C, and the light time is 12 hours. Intensity is 2000lx, during processing in the artificial climate box, the water content of river sand in the yarn bag remains on 10~13% mass fraction; Seed when observing that 50% of the seeds are broken in the yarn bag;

[0045] (4) Seedbed preparation

[0046] Select loam, and add humus and organic fertilizer in the loam tillage layer and mix evenly with the tillage layer soil to make the seedling field, the addi...

Abstract

The invention discloses a method for increasing the emergence rate of hemsleya amabilis seeds. The method includes the steps of seed fine selection, seed processing and storage, seed processing before sowing, seedbed preparing, sowing and seedling culture field management. The seeds and wet river sand are evenly mixed, contained in a sand bag and stored in a refrigerator at the temperature of 1-6 DEG C; before sowing, the seeds are placed indoors for 1-2 days at the temperature of 15-18 DEG C after the river sand rubs seed husks, germination acceleration is conducted in an artificial climate cabinet, the temperature is 20+ / -1 DEG C, illumination time lasts for 10-12 hours, light intensity is 2000lx, and the water content of the river sand is 10-13%; leaf mold and organic fertilizer are added into a seedling culture field soil tillage layer, bactericide is sprayed on the surface of a seedling culture field, a seedbed is ditched, mixed substrates are placed in ditches, topdressing is carried out once in early July and late August in the sowing year, and after sprout tumble in October, the surface of the cabinet is covered with farmyard manure; compound fertilizer is applied in early July and late August in the second year, the emergence rate of the hemsleya amabilis seeds is over 80%, emergence time is short, and seedlings are orderly and strong.

Description

technical field [0001] The invention relates to a method capable of effectively improving the germination rate of snow gall seeds, belonging to the technical field of agronomy. Background technique [0002] Hemsleya chinensis is a perennial climbing herb of Cucurbitaceae Hemsleya chinensis Cogn. Ex Forbes et Hemsl., Hemsleya macrosperma C.Y.Wu and Hemsleya amabilis Diels are mainly used as medicine. Cucurbitacin mainly contains Cucurbitacin IIa, Cucurbitacin IIb, Cucurbitacin saponin and so on. Snow Gallbladder has the effect of clearing heat and detoxifying, invigorating the stomach and relieving pain. It can be used to treat stomach pain, ulcer disease, upper respiratory tract infection, bronchitis, pneumonia, bacillary dysentery, enteritis, urinary tract infection, sepsis and other infections. Villagers in some natural distribution areas of snow gall in Guizhou, Sichuan, Yunnan and other provinces often use snow gall to treat enteritis and dysentery of large livestock su...
