METHOD FOR GROWING SUNFLOWER HYBRID SEED

摘要

A method for growing sunflower hybrid seed consists in field pretreating, sowing of regions for parent hybrid forms, providing group isolation thereof at the mass florification period by means of constructions with net coating and separate harvest. In autumn while field pretreating marking and placement of elements of tunnel construction is realized in the form of equidistant rows of posts with longitudinal flexible connective elements on the tops. In spring next nearest inter-row strip is sowed with sunflower seed and prior to its isolation along the perimeter of each strip under crop furrows are made to fasten ends of kapron net by which strips under crop are covered by means of neighboring rows of posts. During spring and summer fallow strips between strips under crop are cultivated and prepared for sowing sunflower seed next year.
