What does Guyu mean? What should be paid attention to in crop management during Guyu season? After Qingming, Guyu's solar terms are coming soon. Some friends still don't know what Gu Yu means. What are the techniques for crop management in Gu Yu season? Let the special fertilizer expert Baft take you to understand what is Gu Yu.
Gu Yu is one of the twenty-four solar terms of the lunar calendar. Around April 20th of the solar calendar each year, the sun reaches the position of 30 degrees of the Yellow Longitude, which is Gu Yu. Literally, it means "sowing rain".
The ancients once said that "rain rains a hundred valleys". "Clear snow, Guyu break frost", meteorological experts said that Guyu is the last solar term in the spring, Guyu
The arrival of solar terms means that the cold wave weather has basically ended, the temperature has started to rise, and rain has increased. During this period, rain was very useful for the growth and development of cereal crops.
use. Overwintering crops require rainwater to facilitate the return to the jointing season, and spring-sown crops also need rainwater to sow seedlings. Rainwater is greatly beneficial to the growth of cereal crops, so it is called "rain rain".
With the coming of Gu Yu, it reminds the farmers that it is the busy season for planting farmers. Due to the unique nature of the climate, we still forget that we should do a good job of crop management in the rainy season, and "plant" the next good start. With the rise of temperature and the increase of rain, crop growth has entered the best season. Therefore, the valley rain season is also the best period for crop management. At this time, planting and seeding became the main farm work for farmers.
Knowing what Gu Yu means, we can see the importance of crop management during Gu Yu. Since it is the best time for crops to grow, what aspects of crop management should we pay attention to during the rainy season?
The rain increased after the valley rain, which provided sufficient moisture for the crops to resume growth in spring, and also created conditions for spring planting. This season is a good season for early rice transplanting and planting of cotton, spring corn and other crops. It is necessary to plant early rice in time to plant cotton and spring corn in a timely manner while preventing crop diseases. People in the south of the Yangtze River are busy cultivating Field, fertilizing, transplanting seedlings, preparing to grow rice. Tea farmers are busy collecting spring tea and making tea, which can be described as thousands of miles of green and thousands of miles of fragrance. Wheat in the northern region is in the growing season. It is necessary to pay attention to preventing drought and moisture, preventing rust, powdery mildew, wheat aphids and other pests and diseases, removing smuts, and doing a good job of preventing "cold spring" and hail. Farmers planting corn have also begun to cultivate land, fertilize, and sow seeds to prevent infestation by soil silkworms.
Valley Rain Season Crop Management: Vegetables
1. Vegetable cultivation in the open field. Tomatoes, cucumbers, Chinese cabbages and other crops planted for impotence seedlings before Gu Yu should be irrigated with dark water to cover the film to promote slow seedlings. Low-temperature refining should be carried out 7-10 days before planting to adapt to the open field growth.
2. Do a good job of controlling diseases and insect pests, for downy mildew, powdery mildew, blight, blight, etc. of melons, leaf mold and leaf spot of eggplants, and aphids, whitefly, tea yellow mite (tender Insect pests such as spider mites) and spotted flies have been strengthened with pesticide control.
Crop Management in the Rainy Season: Food Crops
1. As the saying goes, "Before Gu Yu, grow cotton well" and then say: "Gu Yu doesn't grow flowers, but the heart crawls like a crab." Since ancient times, cotton farmers have used the Valley Rain Festival as an index of cotton sowing, and compiled them into proverbs, which have been passed down from generation to generation.
2. Guyu solar terms If the temperature is too high and the rain is frequent, it will cause the disease and pest of Sanmai to occur and spread. Special fertilizer expert Baft reminded the farmers to do a good job in preventing and controlling the three wheat diseases and insect pests according to weather changes.
Valley Rain Season Crop Management: Fruit Trees
1.Young orchard
Fertilize spring shoots and fertilize newly-grown plants from "Big Cold" to "Lichun". If the new shoots turn green slowly, top root can be applied. Green manure is harvested and buried in winter, and flower buds and buds are removed. Orchards should be ditched, drainage work should be done well, and trunks should be sanded to prevent the damage of Monochamus alternatus. Prepare the soil for sowing green manure. Spraying to control red spider, malignant leaf worm, psyllid, orange lair, aphid and scab, anthracnose, ulcer.
2. Adult Fruiting Tree
(1) Fertilization after flowering: Especially for trees with a large amount of fruit and weak tree vigor, when the spring shoots turn green after Xiehua, applying a quick-acting fertilizer can protect the fruit. (2) Fruit thinning: Pears usually start thinning two weeks after falling and end within 20 days. The earlier the fruit is cleared, the better. (3) Strengthen soil management: carry out soil cultivation, cultivating, and dredging drainage projects. (4) Prevention of pests and spring shoots: focus on prevention and treatment of scabies, ulcers, anthracnose, red spiders, flower buds, scarabs, etc. (5) Controlling spring shoots: Strong topping of the 30-40 cm shoots of the long-falling fruit trees. Only 2-3 spring shoots of citrus clusters are growing, and the rest are sparse.
