Embodiment 1
[0018] This embodiment is compared with the potted plants without soil acidity adjustment, and no treatment at the flowering and pod setting stages.
[0019] A method for promoting lupine pod formation and improving seed yield, comprising the following steps:
[0020] 1. Low-temperature vernalization: select healthy and plump lupine seeds, soak them in distilled water for 6 hours to fully absorb water, put them in a mesh bag, and put them in a refrigerator at 3°C-5°C for 15-20 days, and use them every 5 days Rinse once with distilled water, place at room temperature for 5-8 hours to activate related enzyme activities, and then sow on the prepared seedbed.
[0021] 2. Pot soil configuration and acidity adjustment: mix evenly according to the surface red loam: peat soil = 6:2, put it into a 35cm×26cm nutrition bag, mix 6g of sulfur powder into each pot of nutrition soil, and the soil pH value is 5.5-6.0. The control nutrient soil was not mixed with sulfur powder.

Embodiment 2
[0029] This embodiment is compared with no low temperature treatment, no supplementary light and greenhouse film treatment.
[0030] A method for promoting lupine pod formation and improving seed yield, comprising the following steps:
[0031] 1. Low-temperature vernalization: select healthy and plump lupine seeds, soak them in distilled water for 6 hours to fully absorb water, put them in a mesh bag, and put them in a refrigerator at 3°C-5°C for 15-20 days, and use them every 5 days Rinse once with distilled water, place at room temperature for 5-8 hours to activate related enzyme activities, and then sow on the prepared seedbed. The control seeds were sown directly after soaking in distilled water for 6 hours.
[0032] 2. Pot soil configuration and acidity adjustment: mix evenly according to the surface red loam: peat soil = 6:2, put it into a 35cm×26cm nutrition bag, mix 6g of sulfur powder into each pot of nutrition soil, and the soil pH value is 5.5-6.0.

Abstract
Disclosed is a method for promoting lupin pod bearing and improving the seed yield.According to the method, the seed yield of lupin is improved through low-temperature vernalization and soil pH value adjustment with the combination of humic acid fertilizer application, light treatment, temperature adjustment and reagent application of a flowering phase and a pod bearing period.The method comprises the main steps that 1, seeds are soaked with distilled water for 6 h, and intermittent low-temperature treatment is performed for 15-20 d; 2, potted nutrition soil is mixed with sulfur powder to lower the pH value; 3, 4 g of compound fertilizer is applied five times in each pot within the growth period, and 3 g of humic acid fertilizer is applied three times in each pot; 4, 13.5 h of illumination is ensured every day on the last ten days of January; 5, temperature is increased in the earlier growth stage, and cooling is performed at the later stage; 6, 500 mg / L monopotassium phosphate and a 0.1% borax mixed solution are sprayed two times in the flowering stage; 7, after pod bearing, 300 mg / L monopotassium phosphate, 10 mg / L heteroauxin and a 0.1% borax mixed solution are applied five times.By adopting the method for lupin planting, flowering can be achieved ahead of time, plant senescence is slowed down, pod bearing is promoted, the seed yield is improved, and the technical problem that the seed yield of lupin is low is solved.
Description
technical field [0001] The invention relates to a method for promoting lupine pod formation and increasing seed yield, which belongs to the technical field of flower cultivation. Background technique [0002] Lupine ( Lupins polyphyllus Lindl) belongs to the Fabaceae Papilionaceae Lupine genus of one-year to perennial herbaceous plants, rich in color, is a newly introduced huge garden garden greening flower species that enjoys both flowers and leaves. It can be used for planting in gardens, arranging flower beds and flower mirrors, and is also an important material for flower arrangement. It has a wide range of uses, has high economic, ecological and social benefits, and has a broad market prospect. Jiangxi generally raises seedlings at the end of September and early October, enters the initial flowering period in late March of the following year, enters the full flowering period in mid-April, and harvests seeds in early May. Lupine is native to western North America. It ...
