What are the methods for preventing watermelon fruit cracking in spring
Watermelon fruit cracking can be divided into field cracking and harvest cracking. Field cracking is the bursting of the rind under static conditions, and its main cause is a sudden change in soil conditions. For example, if soil moisture is low during a certain stage of fruit development, fruit development is hindered, and then rain or heavy irrigation suddenly causes soil moisture to surge, the fruit rapidly expands and cracks,...

Spring management of wheat: focus on preventing and controlling the four major harms
How to manage the first spring irrigation and fertilization of wheat? The first spring irrigation and spring fertilization have a great impact on wheat yield. For example: if the wheat is too dense, too sparse, or lodging occurs in the later growth stage, it indicates that the timing of the first spring fertilization and irrigation was problematic. Another example: if the wheat stays green and ripens late, and the grains are shriveled and thin, that indicates your spring water and fertilizer use...

What pesticide is good for preventing Tomato spotted wilt virus disease?
After seedlings are infected with this disease, the young leaves curl and turn a copper-purple color, the leaves have many black spots, the veins on the underside of the leaves turn purple and lose their green color, and the stems develop faded streaky spots. The diseased plants grow slowly or become stunted, drop their leaves, wilt, and shrivel, and yield declines. In severe cases, the plants wilt and die directly. This symptom is easily confused with streak virus. When tomato is at the fru...

What are the methods for preventing lodging in spring wheat?
"Lodging" is one of the main obstacles affecting wheat yield under conditions of high fertilizer and water. In recent years, the promotion and application of plant growth regulators in wheat production has opened up a new way to prevent lodging and promote increased yield, and is an important supporting technical measure for high and stable wheat yields. 1. Spraying paclobutrazol during the wheat jointing stage...

Technical key points for preventing waterlogging during the rapid growth period of lilies
Pre-emergence management: From sowing to around emergence, the main tasks are clearing ditches and draining water well, ensuring the lily field is neither too dry nor waterlogged, and that there is no low-temperature freeze damage, so as to ensure normal growth of the bulb roots. Seedling-stage management is generally during late April or early May; when the seedlings are about 10 cm tall, apply generally 25-50 kg of decomposed rapeseed cake fertilizer per mu, or 30 loads of decomposed pig manure and urine (do not apply chemical fertilizers containing fluorine or chlorine, and even more so do not apply pig manure and urine that has not been composted), applied in furrows or holes, 6-7 cm away from the lily seedlings. Applying too close can easily cause "seedling rot," while applying too far away makes the fertilizer prone to loss. At the same time, during the seedling stage, depending on labor availability, carry out timely cultivation 1-2 times; where conditions permit, cultivate after rain (be sure to cultivate shallowly), with a cultivation depth of 4-6 cm, deeper between rows and shallower between plants.
