1 Change the random miscellaneous stage in the tasseling stage to the staging and miscellaneous stage 1.1 Seedling stage combination and constant seedling, according to the features of the father, female parent inbred lines, leaf color, leaf shape, growth potential, etc. . 1.2 During the jointing stage, strict decontamination shall be carried out to the tall and large plants in the field and the inferior plants to ensure that the plant types are in order. 1.3 The removal of pre-abortion male tassels is the key to preserving purity. The remaining miscellaneous strains (mainly suspected strains) must be completely eliminated to prevent miscellaneous plants from loose powder. 2 Remove tassels after removing male parent plants and remove them before tasselling. In the past few years, various seed production enterprises have taken the removal of the mother plant as a measure to further control the seed quality, but the tassel production is often busy, and it is difficult to remove the mother plant. Seed quality does not affect the yield, and it is recommended to remove the mother plantlet during the big bell mouth period. This will reduce the cumbersomeness of the seed producer in removing the mother plant, and at this time the determination of the mother plant has been compared. Accurately, it has achieved the effect of saving time and effort.†3 “Mopping†to become “practicalâ€. In recent years, the “Technical Regulations for Hybrid Maize Seed Production†formulated by various seed production enterprises is as follows: To the "male and no male, male and female do not meet each other." But often because of the different varieties, the female parent who caused the loose powder was cut off and the spike was "headed" when checking and accepting, so it had to be extended. Tapping time, Therefore, it is necessary to adopt “practical†tassels (forbidden to strip and emasculate, if necessary, 1-2 leaves) depending on the variety, which will not only reduce tasseling, but also affect seed quality. Turning a single seed production contract into a continuous adjustment of the rural industrial structure combined with the use of land use rights and the participation of seed production contracts, the peasants’ living standards have been continuously improved, farmers’ ideology has changed, and the rapid development of the seed production industry has been established. The foundation, however, leaves enterprises with headaches because farmers’ land use rights are autonomous, and the left side seed production and the right field matter often affect the purity of seeds (sinking powder). Therefore, the seed production enterprises must use the land use rights of farmers. The voluntary shareholding of enterprises is combined with past seed production contracts, because only in this way can the income of farmers be guaranteed and farmers can rest assured that what is more important is that farmers participate in business operations as shareholders and greatly increase the enthusiasm of farmers and the quality of seed production. It will also be ensured, and in the face of China’s accession to the WTO, the implementation of the combination of the two will be imperative. Edit
