The sweet glutinous corn in the south is mainly spring and autumn, aiming at harvesting fresh ear. Planting patterns include corn crops or rice, corn, and vegetable rotations. In the Pearl River Delta, no-tillage and seedling transplanting are used. Soil preparation Soil preparation includes operations such as pre-grinding, ploughing, deep-separation, rotary ploughing, hoeing, applying basal fertilizers, spraying insecticides, and herbicides, so that deep plowing can be done, and soil can be straightened to provide a deep-seated growth of corn. Loose, fertile soil conditions. At the same time, it can also reduce the incidence of diseases, insects and weeds. 1. Former treatment. The planting patterns in the southern region are diverse. In early season vegetables, wheat, barley, rapeseed, faba bean, potato and other crops are reserved for grabbing live or transplanted corn; uncultivated reserved empty rows can be used to deepen the sun in winter (bauxite ), Loosing the soil, planting after planting before planting; Net planting and wide-bed planting (such as double-60) planting is convenient for mechanization, and can be planted with rotary tilling, machine-casting or artificial planting. Before being used as a paddy field, the rice would be drained in a timely manner after the rice was harvested, and no tillage or ridge cultivation would be performed. In addition, in some areas, backlogging of corn has been promoted to dig acupuncture live technology. 2. Tillage technology. Sweet and glutinous corn have poorer top soil and the soil in the fields cannot be too large. When the soil is set, the soil must be crushed. In the hilly areas of the southern corn-producing areas, small-scale micro-tillage machines are generally used. In the Pingba area, gentle-slope farmland can be used for small- and medium-sized tillage machines for rotary-tillage operations. Promote and promote conservation tillage techniques. Land preparation technology generally depends on the former. Remove residual film weeds. After the harvest, the residual agricultural film, debris, dead leaves and surrounding weeds shall be promptly removed to reduce pollutants and pests and parasites. Deep plowing or deep loosening. Deep plowing or deep plowing can improve the structure of the cultivation layer, which is conducive to air circulation and water storage, and forms a soil environment conducive to the growth of sweet and waxy corn roots. When deep plowing, first deep plowing 20-30 cm deep plowing, and then use the rotary tiller 10-15 cm soil layer smashed, so that the surface formation. Deep plowing should pay attention to four points: First, water should be changed to dry land for early and deep plowing; second, thick soil layer and heavy soil must be ploughed; third, dry and shallow soil on hillside dry land should not be cultivated too deeply; Fourth, sand should not be used for deep plowing. , Cultivate the surface layer. Deep plowing can be combined with applying organic fertilizers. In some areas such as red loam and yellow loam, deep soiling operations can also be carried out. They can be deep-slept once every 2-4 years. In combination with site preparation and ridging, full-bed basal fertilization is applied. Open the ditch for the week. The rainfall in the southern region is large, and corn is extremely susceptible to damage. Before planting and transplanting, ridges and furrows are opened. Generally, the width of the ditch is 20-40 cm. The ditch, gully ditch, and gutter are all supported by three ditches. The gutters communicate with each other, and the internal and external phases are connected to achieve drought irrigation, energy drainage, and waterlogging. The request.
