Is it spring after the shock? Yes

Sting is a spring solar term. Sting is the third of the 24 solar terms, and it is also the third solar term in spring. It is celebrated on March 5 or 6 of the Gregorian calendar every year. The folk proverb says, "When the spring thunder rings, everything grows." "When you wake up, you wake up the hibernating insects." These are the characteristics of the shocking solar terms. Sting means that when the weather gets warmer, the spring thunder begins to sound, awakening the insects that are dormant and hibernating underground. Sting means hiding.

Fear is caused by thunder. The ancients imagined Thor as a bird's beak, a winged god, holding a hammer in one hand and knocking on many drums around his body in the other, making a rumbling thunder. On this shocking day, Raytheon played drums in the sky, and the world also took this opportunity to cover the drums.

What do shock and thunder portend?

The ancient "Huainanzi Astronomical Training" said: "The rain nails for fifteen days, which will make the thunder sting louder than the clock in the forest." The rolling spring thunder awakens all sleeping things and tells us that spring is coming. Among the twenty-four solar terms gods depicted by folk painters, the solar terms of "the scenery" are usually drawn with chisels and hammers. Sting is closely related to Thor. Because it is generally believed that it is the rolling thunder in spring that awakens the life in the dormant place. Because of this, whether it thunders or not is regarded as a symbolic sign of the weather in a year. If the spring thunder rolls over the thorn, farmers will think it is a good sign of a bumper harvest.

As the saying goes, "Beat Lei Zhen and Gu Mi" and "Beat Lei Zhen Remy like mud". If it thunders before the earthquake, it will violate the law of solar terms and indicate that the year is not good. In the farmer's proverb, it is "thunder can't move, people eat dog food." There is also a saying that "it thundered before the earthquake and the clouds opened for forty-nine days." There is a word "insect" under the word "sting", so Hubei, Guizhou and other places think that if it thunders on the day of sting, there will be many poisonous insects in summer. The local proverb "there are thunder in the sting, insects and snakes in groups".

What is planted in the solar terms?

Tomato, pepper, eggplant, cucumber

Greenhouse vegetables, such as tomatoes, peppers, eggplants and cucumbers, began to be planted during the solar term. Cucumbers, zucchini and tomatoes in the overwintering greenhouse should start topdressing, watering and strengthening pest control. This period is a crucial period to strive for output and benefit.

watermelon

Watermelons cultivated with plastic film in the middle and early days of solar terms or in early spring should also be raised in a small arch shed, and the seedling age is about 30 days. At present, attention should still be paid to the management of temperature and temperature difference between day and night in order to cultivate strong seedlings and flower bud differentiation.

Onions and leeks

Around the vernal equinox, green onions began to grow seedlings, and spring leeks also began to grow seedlings.

Green-skinned zucchini

In spring, plastic film cultivation began to raise seedlings.

Spring cabbage, radish, carrot; Pepper seedling raising of wheat and melon began.

The main activities that shocked farming

Cutting grass in early spring

This is the main measure of wheat field management in early spring. Cutting grass can reduce soil moisture evaporation, improve soil ventilation, raise soil temperature and eliminate weeds. The favorable time for weeding in early spring is "topping stage", that is, when the "topsoil" is frozen for 2 cm, the effect of moisture conservation is the best, which is beneficial to the early greening, early rooting and strong seedling of wheat. When you hoe the ground, you should adapt to the ground and adapt to the seedlings. For late-maturing wheat fields, the first hoe should be shallow to prevent root damage and seedling pressure; For wheat fields with flourishing seedlings and overgrown weeds, deep ploughing and root cutting should be carried out in the rising period, and the tillage depth should be about 10cm. Old roots should be cut off and sprayed with new roots, and then compacted after ploughing, so as to control the above-ground growth, promote the root system to be solid, and turn vigorous seedlings into strong seedlings. The first hoe should be shallow in early spring, and the hoe will gradually deepen with the gradual increase of temperature.

Rational operation of the first fertilizer and water to promote balanced production increase of all kinds of wheat fields

1, more prosperous seedlings: mainly early sowing and large sowing amount of wheat. The main reason is that the sowing date is relatively early and the temperature is high in autumn and early winter, which leads to the older seedlings and vigorous seedlings. And the sowing amount is too large, the soil moisture after sowing is good, and the emergence rate is high, which leads to the formation of strong seedlings for large groups. The specific performance is that many plots have been closed.

Strictly control turning green fertilizer and topdressing fertilizer at jointing and booting stage. The green-returning fertilizer in traditional cultivation techniques is not only inefficient, but also easy to cause vigorous growth and lodging in the later stage. Fertilization and population growth should be strictly controlled before jointing. At jointing stage (when three leaves are pulled out), the yellowing phenomenon of wheat seedlings is obvious, and 45% multi-element compound fertilizer (N, P2O5 and K2O are all 15%) 15-20kg, urea 8- 10kg (or 3-0kg at jointing stage) If the soil moisture is insufficient during topdressing, it should be irrigated immediately after topdressing to save water.

2. Sowing seedlings late: mainly the sweet potato stubble or Chinese herbal medicine stubble of wheat is sowed late, because the wheat is sowed too late after the sweet potato or Chinese herbal medicine is harvested. Many plots have "a needle" or even "a cover in the soil". Because of the large sowing amount of late-sowing wheat, most of the late-sowing wheat seedlings are relatively sufficient at present, so the cultivation technique of single-stem wheat should be adopted.

Use spring fertilizer and then jointing fertilizer. When the number of seedlings in the field can reach 90%- 100% of the local suitable panicle number (in Shijiazhuang, for example, the number of seedlings per 666.7 square meters is 400,000-450,000), no spring fertilizer is applied, but at the jointing stage, when the small tillers in the field begin to die obviously, the multi-component compound fertilizer is topdressing 15-20 kg of wheat per 666.7 square meters. If the number of seedlings in the field is too small when turning green, green manure should be topdressing as soon as possible to promote tillering, with urea 8- 10 kg per 666.7 square meters of wheat and urea 5- 10 kg at jointing stage.

3. Other wheat fields: For wheat fields with good soil moisture in Miao Zhuang, the time for fertilizer and water management should be determined according to soil fertility and seedling conditions. Wheat fields with poor soil fertility and small population can be topdressed and watered at the beginning of rising; Wheat fields with good fertility and large population can be watered at jointing stage by topdressing, generally 20-25 kg of topdressing urea per mu. Due to the condition of waterless irrigation in dryland wheat fields, the key point of fertilizer and water management is to borrow soil moisture for topdressing, which can be ditched and topdressing after the soil returns to pulp in early spring or after rain. Generally, topdressing urea is about 20 kg per mu, and topdressing should be applied deeply and buried strictly.

Chemical weeding, chemical control and lodging prevention

When the temperature is appropriate, tribenuron-methyl or other herbicides should be used for chemical weeding before the wheat turns green to jointing stage. Before jointing stage, paclobutrazol or Zhuangfeng 'an was used to control lodging of tall varieties and wheat fields at risk of lodging.

Early control of pests and diseases

As the temperature rises gradually in spring, wheat diseases and insect pests begin to occur, so we should pay close attention to early prevention and early treatment, and focus on preventing and controlling wheat take-all disease, wheat spider and midges in spring; Selecting insecticides and fungicides in time to control wheat aphids and wheat powdery mildew after heading. Control wheat take-all disease, control wheat spider and control wheat midge.
