The roots of the lumber are well developed and deep into the soil, and should be chosen for a deep-dry farming layer, which is rich in soil, and which is highly adaptable to the soil, especially in soil with high levels of deep organic content. The seeding is preceded by a deep flipping of the tungsten, which is one metre and five metres wide, and a ditch 20 cm wide, with two rows per twig, with a range of 40 to 50 cm, and a base fertilizer that can be applied to 15 kg of compound fertilizer. Attention needs to be drawn to the fact that light crops are not too dense. Before seeding, the land is ploughed to 20-30 centimetres, applied base fat and 20 kilograms of compound fat. The rain-fed areas of the south will be made of 1. 2 metres wide, with open drains of 20-30 centimetres, the north in the form of flat or high cultivation, the south in february-june and the north in the middle of may. Owing to slow growth in the preceding period, harvests did not begin until july, so that land use could be increased between other vegetables with shorter reproductive periods。
The seedlings are broadcast live: 12 hours before planting, 20-25°c warm water is immersed and then dried, 48 hours of seeding at 25-30°c, half of the seed is seeded in white, 80 cm by row and 50 cm by poaching, first pouring bottom water, 2-3 cm per den, 2-3 cm by overland, around 2,000 cm per acre, with a seedage of about 0. 5 kg. They can also grow. The sunflowers are live and growable. In june, the planting season was set. Before seeding, 2-3 days can be soaked to allow early seeding. If it's live, it's 2 to 3 grains per den, with about 300 to 500 grams per acre. If a seedling is moved, the seedbed is prepared, the seeds are distributed directly, and the seed leaves are planted between 3 and 4. Seeding period: if seedlings are used, they are usually grown in late march, early april and late april, and are then fed to base fat, and are usually seeded 24 hours before sowing. Seymour is followed by the control of the temperature inside the bed in order to prevent high temperature burning of the seedlings and to ventilate in a timely manner. Pre-plantation requires seedlings, as farmers who have had cotton seedlings are aware that they are essentially similar to the management of cotton seedlings. If farmers are using the edges to plant a small amount of live broadcasting. The field moves: to tan, to fertilize, to detached base fat, to compound 25 kg, to have a density of less than 2,000 plants per acre and to move on a single line. At the beginning of may, the fertilisation is applied in a timely manner after the fertilisation, once at the flowering end, with a heavy weight of 20 kg of compound fat, and later with a strong seedling and, if it is not, with fertilizer.
