Breeding methods:
Sowing and breeding in the autumn, at 21-30 ℃ high temperature germination and tidy. The production of lupine in the production of more than sowing, spring and autumn can be broadcast, March spring sowing, lupine but spring sowing growing season in the summer, affected by high temperature heat, can lead to some varieties of non-flowering or flowering plant ratio is low, poor effect. Under the natural conditions of autumn sowing flowering early and growing well, 9 to mid-October sowing, flowering the following year from April to June. 72 holes or 128 holes on-demand, coverage. Nursery soil should be loose evenly, breathable water, dedicated nursery soil or peat soil, perlite mixed use as well. Seeds larger, common or coated, about 40 capsules per gram. Germination temperature of about 25 ℃, to ensure that the media moist, 7 to 10 days of seed germination, germination rate.
Cultivation techniques:

1, transplanting seedlings: lupine soybean seedling 30-35 days, until the leaves are completely launched after the transplanted seedlings. Lupine root series developed, moved to retain the original soil, in order to facilitate the slow seedlings. Soil pH adjustment, according to the growth habits of lupine, cultivation and control of the cultivation of the substrate during the pH (pH) for the normal growth and flowering lupine is essential. In general, the easiest and effective method of regulation is to apply sulfur powder to the culture substrate. As the sulfur in the matrix to take some time to break down (about 40 days or more) to play a regulatory role, so the application should be carried out as soon as possible, usually in the 2 to 3 leaves after the emergence of real leaves, the amount of cultivation as the original PH. In addition, ferrous sulfate, aluminum sulfate and other acidic fertilizer has a short-term effect of reducing the pH value, but too high salt ion concentration will cause poisonous plant roots, the production to be less.
