High-yield sunflower planting method

Abstract

The invention discloses a high-yield sunflower planting method. The method includes the steps of 1 land selection, 2 soil preparation and base fertilizer applying, 3 seed selection, 4 seed treatment, 5 sowing, 6 field management, 7 topdressing, 8 disease and pest control and 9 harvesting. The field management includes watering, filling the gaps with seedlings, weeding, supplementary pollination and pruning. The high-yield sunflower planting method selects hybrid sunflower seeds to obtain cultivated sunflowers of good quality, is environmentally friendly to meet the ornamental needs of people and not cause environmental pollution and has significant economic and social benefits. Furthermore, the fruit of the sunflowers cultivated from the hybrid sunflower seeds is good in quality, high in yield and good in commodity characteristic.

Description

field of invention [0001] The invention relates to the field of plant cultivation, in particular to a high-yield sunflower planting method. Background technique [0002] Sunflower is also known as sunflower, sunflower, and sun flower. Its whole body is full of treasures. In addition to direct oil extraction from seeds, the by-products of refined oil are excellent cosmetic raw materials; oil cakes after oil extraction are rich in nutrients, including nitrogen compounds. It accounts for 41.5%, cellulose accounts for 16.0%, and mineral content accounts for about 6.7%. It also contains a small amount of lipids, and no toxic substances have been found. Oil cakes contain about 30% to 36% protein, including rich sulfur-containing amino acids; albumin accounts for 55% to 60%, albumin accounts for 17% to 23%, and gluten accounts for 11% to 17%; and other oil crops In comparison, sunflower oil cake has higher nutritional value as animal feed, and is the concentrated feed for poultry ...

Problems solved by technology

Its crude protein content is similar to that of oat grains and barley grains, but its crude fat content is more than double; at the same time, sunflower pan contains a lot of pectin, which is an excellent concentrate feed for pigs after being dried and crushed; it is suitable for other roughage feeds Add some sunflower bran, boil it with water and it will become a viscous bran porridge, which pigs prefer to eat; sunflower stalks are thick, long and hard, and can be used as supports for vegetable cultivation. Sunflower is also a good nectar source crop, with a longer flowering period, more honey juice, and a large amount of pollen. A box of bees can be raised on 3 to 5 acres of land. Promote, both improved the yield of sunflower, can hold honeybee concurrently again, but, because improper planting makes most of sunflower only bloom but not bear fruit, this makes the yield of sunflower reduce greatly; solved problem
