Q: In cold weather, can watermelon still drip? What fertilizer? There is now a cracking phenomenon.
A: Now that there has been a split of the melon, drip irrigation is even more undesirable in cold weather. In addition, the cracking of melons is mainly caused by sudden flooding of water in the absence of water, resulting in an instantaneous increase in moisture; partial application of nitrogen fertilizer, phosphorus phosphorus, potassium, calcium and boron deficiency, neglect of good farmyard manure and application of compound microbial fertilizer can also lead to split melon Improper use of hormones can also cause melons to crack. Coupled with the rapid growth of Jingxin melon bags, once the control is not good, fertilizer and water are particularly likely to cause rapid growth of melon, melon skin growth is slow, resulting in split melon phenomenon. You can use the amino acid + calcium fertilizer for foliar spray, spray once every 7 days, even spray 2-3 times to prevent. If there is more cracking, it can be added with protective bactericide such as zessenlian and azoxystrobin to prevent infection by bacteria.
Question: The guam seedlings in the sheds are not long in the main vines, but are grown beside them. How should they be controlled?
A: The growth of lateral vines inhibits the growth of the main vines and removes side vines in time to promote the growth of the main vines. Cucumber to the main vine flowering melon, remove the side of the main cranberry after the vines do not stay too much, the leaf surface spray of seaweed extract powder or amino acid foliar fertilizer + potassium dihydrogen phosphate, to promote the main vine growth, pouring two water When appropriate, increase fulvic acid or humic acid with balanced water-soluble fertilizers for fertilization.
Q: On the same ridge, Hong Yan and Jiu Xiang grow well. Sweet Charlie grew up like this. Is it sick when nursery?
A: There are several situations that can cause this phenomenon: First, root damage. Watering, unreasonable use of fertilizer, and excessively high ground temperature have resulted in root injury or growth inhibition and poor leaf growth. The second is high temperature caused by high temperature barriers. Third, different varieties of strawberries have different resistance to fertilizers and the environment. Some varieties are relatively sensitive. You can use amino acid foliar fertilizer + high-phosphorus water soluble fertilizer + 70% symlink spray plus leaching root, root and strong seedlings, while preventing infection.
Q: Do potato seeds grow well in advance? When sowing, what should be done normally?
Answer: There are two ways to sow potatoes: one is to plant seeds after cutting, artificial sowing is suitable for shed species, and the other is to sow directly after cutting, which can be artificially sown or machine sown, suitable for open air. The planting model in Shandong is to prepare potato seeds 15-20 days before sowing. After two days of drying, the potatoes are ready to be cut, and seed dressing is performed. The planting area in the arch shed is first used for germination, and then germination followed by manual sowing. After the open-air planting after March, after cutting, dressing (sterilization and healing wounds) is performed. The machine sows the soil and covers the film. This method can also spray the enclosed herbicide before the film is applied. After about 15-20 days, the potatoes begin to grow. Germinate and grow.
Q: What kind of disease is the first time we grow beans?
A: The yellowing of the heart may be caused by several reasons: First, the pesticide concentration is too high or the hormone leaf fertilizer is used improperly; the second is the lack of zinc and iron and other elements; third, the soil drought suddenly poured cold water and deep-fried roots, and the water and fertilizer concentration is too high. Root damage caused by factors such as soil contamination or adverse environmental conditions can also lead to yellowing of the heart. It is recommended to relieve the yellowing of the heart and relieve the distorted symptoms first, and then to prevent rust again. Use foliar fertilizers containing alginic acid or chitin, then add foliar fertilizer (Azathiophene) and tebuconazole to spray the leaves first, so that the leaves can be alleviated first, and then the roots should be cultivated. On the wells of the water, it is best to over the pool to dry it, to avoid watering at noon, to prevent the roots from affecting the roots of the absorption, in the water when spraying some humic acid or fulvic acid water soluble fertilizer.
