Method for improving quality and increasing number of collard seed production

Abstract

The invention discloses a method for improving the quality and increasing the number of collard seed production. The method comprises the steps of sowing, seedling cultivating, rational fertilizing, field planting, managing, clipping, trimming, and harvesting according to the maturity of branches and seed pods. By the way of cutting off tops of newly flowering branches each time, the number of small seeds is reduced, nutrition loss is reduced, nutrition for plant branches blossoming and having seeds can be more sufficient, and thousand seed weight of the seeds can be increased; moreover, plant lodging caused after fruit setting is effectively reduced, so that the yield and the germination rate are increased. Harvesting is carried out in time by observing the maturity of the branches and the seed pods, the seeds mature after being hung for a short term, the postharvest humidity is reduced, the germination condition is destroyed, and germination in the seed pods can be effectively reduced. The method is simple, effective, and capable of solving the problems of collard seed production, and achieves the purposes of increasing the yield, improving the seed quality and increasing benefits.

Description

Technical field: [0001] The invention belongs to the field of cultivation technology, relates to a seed production technology, in particular to a cultivation method for improving the quantity and quality of ornamental kale seed production. technical background: [0002] Ornamental kale (Brassica oleracea var.acephala f.tricolor H or t.) is a variety of Brassica oleracea in the family Brassicaceae. It is native to the coasts of the Mediterranean Sea to the North Sea in Europe. It is a biennial herb plant, mainly for foliage. The shape is beautiful and changeable, the color of the heart leaves is gorgeous like flowers, and the cold resistance is strong. It is the first choice for viewing in late autumn, winter and early spring. The horticultural varieties have various shapes. According to the height, they can be divided into tall and short types; Round leaves, wavy leaves, lobed leaves and deeply lobed leaves; according to the color, the edge leaves are emerald green, dark gre...

AI Technical Summary

Problems solved by technology

However, the seed coats of some varieties of ornamental kale seeds are relatively thin, and they are easy to germinate on the plants. In the process of seed propagation and seed production, there are many phenomena of damaged seed coats, many germinated seeds, and many small seeds. Affects the quality of the seeds and reduces the germination rate
