In the hot summer, eating watermelon to cool off is a very pleasant thing, today Fenggong automatic fan sorted out the watermelon fertilization in the greenhouse need to pay attention to 4 things:
1. Fertilization scheme in high temperature period: watermelon grows quickly in high temperature season, and the nutrients provided should be comprehensive and easy to absorb quickly. The simple use of compound fertilizer is difficult to meet the needs of watermelon for rapid absorption of whole nutrients in time, so watermelon in the high temperature season can be according to the following scheme: fertilization: good water solubility, watermelon absorption fast and containing 10 kinds of nutrients Cuikang Chong fertilization 500~750 grams + Cuikang root liquid 400 grams / mu as top dressing with water irrigation, once every 10 days at intervals, in time to meet the fertility needs of watermelons in the high temperature season. At the same time, in order to adjust the soil structure, prevent soil compaction, improve fertilizer utilization rate, and delay root aging, each batch of melon can be added 1 time of Saide seaweed fertilizer (5 kg/mu), which is conducive to maintaining the growth of watermelon and preventing premature aging.
2. Potassium and magnesium
supplementation to prevent premature aging: In the high temperature season of summer, watermelon is prone to yellow old leaves, scorched leaves and potassium and magnesium deficiency symptoms, short leaf life and early aging, which seriously affects the later yield. Foliar rapid potassium and magnesium supplementation can be used Cuikang Baoli 700 times foliar spray, once every 7~10 days; Or add potassium magnesium sulfate 10 kg/mu drip irrigation when soil fertilization, combined with the application of Saide seaweed fertilizer, the effect is better.
3. Supplement trace elements: spray 1~2 times with Cuikang Jinpeng liquid 1500 times liquid during the sitting melon to effectively prevent deformed melon, hollow melon, etc.; During the expansion period (egg size), spray 1~2 times with Cuikang Shengli Liquid 600 times + Cuikang Baoli (or Cuikang Gold Potassium) 700 times, which can effectively prevent watermelon white tendon or yellow heart, and reduce thick-skinned melon, improve the quality of watermelon, and delay premature aging.
4. Restore growth: melon orchards with serious decline of vine potential; With Cuikang high nitrogen flushing fertilization 500 g + Cuikang root liquid 300 g/mu drip irrigation 2~3 times (including one application of Saide seaweed fertilizer 10 kg/mu), can quickly restore growth and delay root aging.
The flesh of watermelon is red and yellow. If R is used to represent the gene that controls the dominant trait, r is used to represent the gene that controls the recessive trait. With two watermelon plants crossed, it can be inferred from the genetic results shown in the table that yellow (or yellow flesh) is a recessive trait. Try to write the genetic composition RR of the red flesh in the offspring watermelon in the table.
