When will Xi 'an wheat mature?

Question 1:Xi 'an's wheat ripens from the end of June to the beginning of July. When will the harvest be completed?

Question 2: In what month did 2:Xi 'an harvest wheat? Five minutes in June.

Question 3: When is the wheat ripe? According to different varieties of wheat sown in different regions, different sowing dates of wheat in different regions will lead to different maturity of wheat. Winter wheat area: generally sow in autumn (65438+1around the end of September), and harvest will be completed at the end of June-early July of the following year.

Spring wheat area: Generally, the seeds are sown from south to north in turn from Qingming to mid-May (high latitude areas recover later), and the harvest is completed from mid-July to late August. In the northernmost Daxinganling region, wheat ripens in mid-August at the earliest and in early September at the latest.

Question 4: In which month did 4:Xi 'an harvest wheat? Late May and early June.

Question 5: The question of whether the wheat ripens first in Shaanxi or Henan is too broad. The latitudes of Shaanxi and Gansu are not small. Let's put it this way, if the latitude is the same, the maturity time of the two places should be: the time in southeastern Gansu and southeastern Shaanxi (near Hanzhong) is the same; Longzhong (Lanzhou and Dingxi) is later than Shaanxi (near xi 'an); The time in northeast Gansu is the same as that in northern Shaanxi; Most areas in western Gansu are later than those in Shaanxi.

Question 6: Who knows where the wheat ripens at the earliest 5 minutes in Shaanxi and earlier in Weinan? . .

Wheat in China is basically from east to west and from south to north.

As far as Shaanxi Province is concerned, most of southern Shaanxi is rice, most of Guanzhong is wheat, and Weinan is the east gate of Shaanxi, and of course it has gradually matured from here-Xi 'an-Xianyang-Baoji. . .

Question 7: When did 7:Xi 'an's wheat ripen and turn yellow but not yet harvested? This is the last few days! We must hurry. Now the wheat harvest is very fast, and several villages have finished it in one day. Better early than late!

Question 8: What's the difference between wheat in 8:Xi 'an and wheat in Henan? It shouldn't be much difference, not too far.

Wheat is a monocotyledonous plant and a gramineous plant widely cultivated all over the world. The caryopsis of wheat is one of the staple foods of human beings, which can be made into bread, steamed bread, biscuits, noodles and other foods after being ground into flour. After fermentation, it can be made into beer, alcohol, white wine (such as vodka) or biomass fuel. Wheat is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, nicotinic acid, vitamin A and vitamin C, etc.

morphological character

The stalks are erect and clustered, with 6-7 nodes, 60- 100 cm in height and 5-7 mm in diameter. The leaf sheath is loose, phimosis, the lower part is longer than the upper part, and the internodes are short; Ligule membrane, about 65438 0 mm long; Leaf blade long lanceolate. The spike is erect, 5-10cm long (except awn) and1-1.5cm wide; Spikelets contain 3-9 small flowers, and the upper part is underdeveloped; Glumes are ovoid, 6-8 mm long, and the main veins are ridged in the upper part of the back. The teeth extending at the top are about 65438 0 mm long, and the lateral veins and top teeth are not obvious. Lemma oblong-lanceolate, 8- 10 mm long, with or without awning at the top; Palea is about as long as lemma.

Growth habit

Deep soil layer, good structure and deep tillage layer are beneficial to water storage and fertilizer conservation and promote root system development. Soil structure refers to the proportion of solid (organic and inorganic), liquid and gas, which is closely related to soil moisture, air, temperature and nutrients.

Zhu Lou Cun mai Tian

For example, sandy soil and heavy clay have poor structure and are difficult to form high yield.

The average daily temperature of winter varieties is 16 ~ 18℃, semi-winter varieties are 14 ~ 16℃, and the elasticity is 12 ~ 14℃. Temperature and air are affected by geographical latitude and altitude, that is, the higher latitude and altitude, the lower temperature and the earlier sowing date.

Wheat crops with long sunshine time (8 to 12 hours per day), if the sunshine conditions are insufficient. Can't pass the light stage, can't knot, can't bear fruit. The photoperiod of wheat is after vernalization.

Planting technique

Tillage and soil preparation

Tillage and soil preparation can make the topsoil soft, the soil broken flat, the dry and wet conditions suitable, promote the whole emergence of wheat and ensure the coordinated growth of underground and aboveground parts, which is an important link to create high-yield soil conditions. The specific methods vary according to paddy field, dry land and previous crops.

1. Soil preparation for multiple cropping of rice and wheat in wheat fields Due to long-term immersion in paddy fields, the soil is hardened and the permeability is poor, so it is necessary to promote soil maturation through paddy-upland rotation and dry-wet alternation. The characteristics of soil preparation are that when the previous crops are harvested earlier, they should be plowed as soon as possible, and shallow ploughing and fine harrowing should be carried out before the kang soil is fully dried and sown, so that the upper part is soft and the lower part is solid. As a seed-making field of late rice or hybrid rice, due to the short interval between harvesting and sowing, it is necessary to ditch and drain rice seeds when sowing, so as to try to dry the thin slices in the sun for a short time. On the premise of not delaying the timely sowing of wheat, shallow soil preparation can also be done to create a good seedbed and growth foundation for wheat.

2. The soil preparation of dryland wheat should be based on increasing the deep ploughing layer year by year, combined with increasing the application of organic fertilizer and improving water-retaining fertilizer, according to different multiple cropping forms. That is to say, if the previous crops are harvested earlier, such as spring corn, sorghum, tobacco and so on. Clean up the stubble first, then dig the kang soil deeply, let the stubble rot and accept the autumn rain. Use a shallow rake to reduce evaporation after rain. Another kind, such as sweet potato and cotton, has a short harvest period. If conventional methods are used, the sowing date will be delayed, which is one of the important reasons for the low yield of wheat in southwest China. Therefore, on the one hand, it is suggested that the soil between rows should be loosened in the late stage of the previous crop, and then ploughed and leveled when planting wheat; On the other hand, continuous operations such as digging potatoes, leveling, fertilizing and sowing are advocated to ensure timely sowing of wheat.

Question 9: What kind of wheat does Xiaoyan 6 grow in Xi 'an?

Xiaoyan 6 was introduced into wheat by Northwest Institute of Botany after more than 20 years of experimental research.
