Embodiment 1

[0032] Example 1: Step 1. Choose a suitable semi-upright pea variety that eats pods and grains.

[0033] Step 2. Select pea seeds of the same size and soak them with 50% carbendazim 500 times solution for 2 hours, wash the seeds, soak in clean water and fully absorb water, and evenly spot them in the seedling tray with absorbent paper on the bottom for sprouting.

[0034] Step 3. After germination, move to an artificial seedling box at 0°C, 12h light / 12h dark, the light source is a white LED lamp, the rated power is 70W, the lamp beads are evenly arranged, and the light intensity of the lower illumination surface is uniform. Leave it for 15 days for combined treatment of LED light source and temperature.

[0035] Step 4. Sowing in time: Plant the treated pea seeds in the facility greenhouse on September 1st, with a transplanting density of 7000 plants per mu; if the highest temperature during planting is higher than 25°C, a shading net must be set up and the pea will grow throughout ...

Embodiment 2

[0041] Example 2: Step 1. Choose suitable pea varieties that eat pods and grains semi-upright.

[0042] Step 2. Select pea seeds of the same size and soak them with 50% carbendazim 500 times solution for 2 hours, wash the seeds, soak in clean water and fully absorb water, and evenly spot them in a seedling tray with absorbent paper on the bottom to initiate germination.

[0043] Step 3. After germination, move to an artificial seedling box with a temperature of 10°C and 12h light / 12h dark. The light source is a white LED lamp with a rated power of 70W. The lamp beads are evenly arranged and the light intensity of the lower illumination surface is uniform. Leave it for 15 days for combined treatment of LED light source and temperature.

[0044] Step 4. Sowing timely: Plant the treated pea seeds in the facility greenhouse on September 1st, with a transplanting density of 7,500 plants per mu; if the highest temperature during planting is higher than 25°C, set up a shading net. Strictly...

Embodiment 3

[0050] Example 3: Step 1. Choose a semi-upright type suitable for pea that eats pods and grains.

[0051] Step 2. Select pea seeds of the same size and soak them with 50% carbendazim 500 times solution for 2 hours, wash the seeds, soak in clean water and fully absorb water, and evenly spot them in the seedling tray with absorbent paper on the bottom for sprouting.

[0052] Step 3. After germination, move to an artificial seedling box with a temperature of 15°C and 12h light / 12h dark. The light source is a white LED lamp with a rated power of 70W. The lamp beads are evenly arranged and the light intensity of the lower illumination surface is uniform. Leave it for 15 days for combined treatment of LED light source and temperature.

[0053] Step 4. Sowing at the right time: Plant the treated pea seeds in the facility greenhouse on September 1st, with a transplanting density of 8000 plants per mu; if the highest temperature during planting is higher than 25°C, a shading net should be set...

Abstract

The invention discloses a sub-erect type pea early mature promotion method through the combined processing of LED light sources and temperature. The method includes selecting seeds of adaptive sub-erect type peas allowing pods and grains to be edible; soaking the pea seeds through 50% carbendazim 500 times liquid for 2 hours, cleaning the seeds, after soaking the seeds in clean water to absorbing water completely, arranging the seeds in seedling plates with the bottom paved with absorbent paper; transferring the seedlings to an artificial seedling box at the temperature ranging from 0 to 15 DEG C to be in light for 12 hours and in dark for 12 hours regularly for 15 days; sowing to a greenhouse in early September with the density of 7000 to 8000 / mu; mulching a ground film during sowing, erecting a small arch shed when the temperature is lower than 3 DEG C, increasing fertilizer in the seedling, growing, blooming and fruiting periods of the pea, and performing insect and disease proofing treatment; harvesting fresh pods or grains in batches from November, and burying the straws as fertilizer. The method has the advantages that the fresh pea yield can be increased, the growth period is ahead of time, and the economic benefit is increased.

Description

Technical field [0001] The invention belongs to the technical field of crop cultivation, and relates to a method for promoting the early maturity of semi-upright pea through combined treatment of LED light source and temperature. Background technique [0002] Peas (Pisumsativum Linn.) is one of the main open-field legume vegetable crops cultivated in southern China in winter. It has multiple effects on enriching vegetable varieties in southern my country and combining land and cultivation. Pea production in southern China is mainly concentrated in coastal areas such as Jiangsu, Zhejiang, Fujian, Shandong, Anhui and other provinces, with an annual planting area of ​​more than 130,000 hectares. The sowing time is October of the previous year, and the harvest time is generally from mid-April to early May according to different uses. About 40% of the products are used for quick-frozen processing and exported to Japan, South Korea and Southeast Asia, and other products are directly u...
