Time flies so fast, and soon we will usher in the Guyu solar term, which is the last solar term in the spring on the mainland, and the rainfall increases significantly after entering the Guyu solar term. The agricultural proverb says that "the snow is broken during the Qingming Festival, and the rain is broken and the frost is broken", in most parts of the mainland to the Qingming solar term is a symbol of "the end of the snow", and to the Guyu solar term is the symbol of the "final frost", so when it comes to the Guyu solar term, many vegetables that like temperature and heat can be planted.
So what vegetables can be planted in the Guyu solar term? The following 6 kinds of vegetables can be planted with confidence, vegetable farmers should not miss it.
1. Sweet potatoes
Sweet potato is not only an important food crop, but also an important vegetable crop, the agricultural proverb says "Gu Yu planted sweet potato seedlings, a tree can harvest a big basket", it is said that into the valley rain solar term cuttings sweet potato seedlings, sweet potatoes are easy to high yield.
Sweet potato growth cycle is long, it takes almost 5 months from potato seedling cuttings to potato tuber harvest, and sweet potato plants are afraid of frost, frost plants will wither and die, if sweet potato cuttings are too late, then when the frost weather comes in October, the tuber of sweet potato will be reduced because it is not fully expanded;
Special attention: sweet potatoes like to grow in the organic matter content, loose soil plots, such plots are conducive to the full expansion of potato pieces, sweet potatoes will be easier to high yield; secondly, sweet potato plants are afraid of waterlogging, waterlogging will affect the root system and the respiration of potato tubers, the growth of sweet potato tubers will be affected, so we should plant sweet potatoes when ridge cultivation, the ridge cultivation can also improve the temperature difference between day and night of the soil, which is conducive to the accumulation of photosynthetic products, sweet potatoes will be easier to high yield; A nest of sweet potatoes and a handful of ash, sweet potatoes form a large pile", plant ash can not only loosen the soil, but also can add potassium fertilizer to the growth of sweet potatoes, which is very conducive to the high yield of sweet potatoes.
2. Chili peppers
Pepper is a very important vegetable crop, many people like to plant, pepper is not cold-resistant, the average temperature of the day is stable above 15 °C can be transplanted, and the average daily temperature in most parts of the mainland is stable at more than 15 °C, so we can transplant pepper seedlings when entering the valley rain season.
The agricultural proverb says that "pepper planting double does not plant single, sweet potato planting single does not plant double", which means that sweet potato seedlings should be transplanted in a single plant, and one plant is planted in a nest, and the pepper plant is compact and the crown is relatively small, so we can transplant 2 plants per hole when transplanting pepper seedlings.
The seedling time of the Spring Festival pepper is about 60 days, we should try to transplant the robust pepper seedlings when transplanting the pepper seedlings, the robust pepper seedlings have the characteristics of thick stems, dark green leaf color, developed roots, no diseases and pests, the seedlings will be faster after transplanting, and the stress resistance of the plant will be stronger, which is very helpful to the improvement of pepper yield. When we transplant pepper seedlings, we should try to bring as much soil as possible, do not bury the leaf sheath when transplanting, after transplanting, we water the soil thoroughly, and use straw or shade net for shading, which can prevent pepper seedlings from being burned by the sun, and can speed up the slow seedling.
3. Corn
Corn is not only a food crop, but also a vegetable crop, as the old saying goes, "grain rain planting field", corn is also a temperature-loving crop, the average temperature of the day is lower than 10 °C when the seedlings will emerge slowly, the temperature and humidity of the soil are very suitable for corn seed emergence, so corn can be sown with confidence after the valley rain.
There are many varieties of corn, if it is used as a vegetable, we can plant sweet corn or waxy corn, these two kinds of corn we do not spray herbicides when planting, so as not to cause pesticide damage.
When planting corn, we can sow 2 seeds per hole, combine the land preparation and apply farmhouse fertilizer and compound fertilizer as base fertilizer, when the corn seedlings grow to knee height, we can top apply urea, which can promote the vigorous growth of corn seedlings; when the corn enters the big flare stage (the 11th ~ 12th leaf unfolds), we can apply urea again, which can promote the large ears of corn and the full grains.
Fourth, cucumbers
As the old saying goes, "before and after the valley rain, plant melons and beans", the soil moisture is stable during the valley rain solar term, like the vast majority of melons and bean crops can be planted.
Cucumbers can be transplanted seedlings, can also be directly sown, into the valley rain solar term planting cucumbers we can directly sow, sowing using the size of the row spacing to plant, large row spacing in about 80 cm, small row spacing in about 40 cm, plant spacing in about 40 cm, sowing 3 seeds per hole. When we plant cucumbers, we must not sow too densely, sowing too dense will lead to too closed fields, which will not only lead to serious cucumber flower and fruit drop, but also lead to a high incidence of pests and diseases in the field.
When the first inflorescence of cucumber sets fruit, the plant's demand for nutrients increases, at this time we can combine watering to apply 20 kg of ternary compound fertilizer per mu; when the cucumber enters the full flowering and fruiting stage, the plant's demand for nutrients is the largest, at this time we can spray potassium dihydrogen phosphate foliar fertilizer on the foliar surface, spray once every 7~10 days, spray 2~3 times in a row, can significantly improve the yield and quality of cucumber.
V. Xiangqi
Coriander is an important seasoning vegetable in our life, it is not resistant to high temperatures, when the temperature exceeds 30 °C, coriander will stop growing, so coriander is not suitable for planting in the hot summer, every spring from the beginning of March to the end of April and mid-August to the end of September is the suitable sowing period of coriander, so we should hurry up and sow coriander after the rain.
The planting of coriander is very simple, planting coriander we choose easy drainage and irrigation, rich in organic matter in the soil, before sowing we have to break the shell of the coriander seeds (with beer bottles or foot soles to crush), which is not only conducive to coriander seedlings, seedlings, but also can speed up the emergence of coriander, after sowing we can water the soil thoroughly.
6. Water spinach
Water spinach has a smooth and tender taste, and many people also like to grow it. Water spinach has strong heat tolerance, so we should not sow too early, sowing too early will be slower, generally we will sow after the rain.
Water spinach we soak the seeds in water for a day and night before sowing, sowing can be sown or strip sowing, covering thin soil after sowing, and watering the soil thoroughly, generally 7~10 days after sowing seedlings. Water spinach likes moisture and fertilizer, we can usually water more, try to keep the soil moist, when the water spinach grows to 5 cm high, we can apply urea, which can promote the vigorous growth of water spinach.
Generally speaking, when the water spinach grows to 30 cm high, we harvest it, and the base of the stem should be retained 2~3 nodes when harvesting, which is conducive to the regeneration of water spinach; after the water spinach is harvested for 1~2 days, we can pour the rotted thin manure water, so that the water spinach can grow vigorously.
In summary, entering the Guyu solar term, we can plant the above 6 kinds of vegetables, and you can prepare in advance.
