Adopting various measures to cultivate large and strong seedlings can increase the number of leaves that grow in banana tissue culture (referred to as tissue culture) seedlings during the ploiding period, and accordingly reduce the number of leaves grown in the field. At the same time, as the seedlings are thick and strong, they grow quickly, they grow quickly, and the growing period of the field is shortened, which can be harvested earlier.
According to the survey, the total number of banana leaves planted in the Guangdong region is 42-48 pieces. Between March and September, an average of 5.3 days grew a new leaf. Using 10-12 leaf-old plants, the plants grow 32-36 new leaves during the field from late August to mid-September, where they can shoot buds, harvest them years ago, avoid low-temperature frost, and achieve annual security. The purpose of improving economic efficiency. After the end of September, the plants were delayed by 1 day for each bud, and the fruit was postponed for 3-7 days. Therefore, the cultivation of strong seedlings during the false period is the key to winning the winter harvest of the year.
First, choose high-quality seedlings planted high-quality tissue culture seedlings virus-free, pure seed, low mutation rate, dark green leaves, leaves more (leaf age more than 2), roots and pseudo-stem stout, can be maintained after prosthesis Strong growth advantage.
Second, false value method
1, to improve the substrate holder to the original 8 cm 10 cm small film to 10 cm 10 cm or more, both to increase the matrix capacity, but also expand the root extension. There is only one plastic nutrient cup in the center of the bottom of the water hole for the props of the implant substrate, and it is covered with a plastic film. The roots are not easy to grow into the nutrition cup and enter the ground. This reduces the damage during planting and is easy to recover after planting.
