Strawberry seedlings "four notes"

In June, strawberries have entered the season of seedling propagation. In order to ensure the quality of new multiplication strawberry seedlings, the following issues need to be noted during the breeding process:

One is to pay attention to weeding and weeding. Shortly after the strawberry female parent was planted, it entered the rainy season. The rainy season is the season with the most rain in the year, and it is also the season for the growth of weeds. Therefore, when the strawberry seedlings are bred, we must do a good job of weeding in order to prevent grass seedlings from appearing.

The second is to pay attention to soil moisture. Strawberry seedlings are grown on the stems of the mother plants. Whether or not the stems can be rooted in time is related to the moisture of the nursery soil. The soil moisture is conducive to root undershoot. Although the strawberry breeding season is in the rainy season, but at this time it is the season with high temperatures, and the soil loses water quickly. If there is continuous high temperature and little rain for more than 10 days, the soil will be arid, affecting the pumping of stem borers and the downside , so the nursery must pay attention to keep the soil moisture.

The third is to remove the diseased, old, and stubble leaves frequently and timely remove the inflorescence on the mother plant. In the process of strawberry breeding, old leaves and diseased leaves will continue to appear. The occurrence of these diseases, old leaves and leaves will provide great convenience for the development of strawberry diseases and insect pests. If they are not cleaned up and removed in time, it will cause diseases and pests in nursery nurseries. Great happening. In addition, the female seedlings will also draw new inflorescences during the growth process and consume plant nutrients, which is not conducive to the propagation of seedlings. Therefore, they must be removed in time to increase the reproduction rate.

The fourth is timely fertilizer. Adequate nutrition is the basis for the continuous reproduction of the female strawberry. Therefore, in the process of breeding strawberry seedlings, it is necessary to constantly supplement fertilizers to meet the nutrients needed for the strawberry seedlings. On the basis of applying base fertilizer, topdressing 2 fertilizers before the end of July, for the first time around July 10th, the top-grade application of ammonium diammonium phosphate and urea (2:1) mixed fertilizer 15 to 20 kg, the second At the end of July, the top-dressing N fertilizer was phosphorus:potassium (15:15:15) compound fertilizer 15-20 kg.
