Generally speaking, in June, Henan entered the wheat harvest season from south to north.
The best time of day to harvest wheat:
Generally, the best time of the day is: 9: 00-11:00; 16:00- 18:00
The maturity of wheat is the main basis for determining whether wheat can be harvested. Wheat grain maturity can be divided into three stages: milk maturity, wax maturity and complete maturity. At the end of wax ripening, the dry matter accumulation of wheat grains reached the peak, with good quality, the highest yield and complete physiological maturity, which was the best season for artificial harvest.
Observation on wax maturity of wheat seeds: generally, it is orange with different shades. After being cut with a knife, the section is waxy and slightly hard, only slightly soft at the abdominal groove, the empty stomach near the abdominal groove has disappeared, and slight nail prints can still be squeezed out on the back of the seed.
The maturity of wheat is different. Generally, it is early in the south and late in the north. The farther north, the later. Generally, it is from June 1 to June 10, which is later in the north.

Winter wheat is harvested in late June and early July; Spring wheat is sown in late March and early April and harvested in the middle and late July.
Wheat growing environment
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. 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.

Key points of spring wheat cultivation techniques
1, strip application, fertilizer matching seeds. Before sowing, apply the fertilizer strip to the ground 9 cm deep, and then sow it to a depth of 3 ~ 4 cm. When the nutrients of wheat grains are exhausted in the three-leaf stage, the fertilizer is just supplied.
2. Apply foot fat. If preparations are made before winter, 2000 kg of organic fertilizer, 2000 kg of ammonium phosphate 15 kg of urea 15 kg will be uniformly applied to the field, and ploughing will be carried out immediately, so that it will be "rich in the belly" and the ploughing depth will reach 20-25 cm. Do not make any preparations before winter, and apply 30 ~ 50kg of standard nitrogen fertilizer, 30 ~ 50kg of standard phosphorus fertilizer and appropriate amount of potassium fertilizer and microelement fertilizer per mu.
3, timely early broadcast, narrow the line spacing. The earlier spring wheat is sown, the better. Wheat has good frost resistance in vernalization stage, and generally there will be no frost damage. Spring wheat has fewer tillers and smaller individuals, and higher yield can be obtained by close planting.
Generally, the row spacing is about 17 cm, or large and small rows, with large rows of 20 cm and small rows of 13 ~ 15 cm. The sowing amount depends on the 1000-grain weight, germination rate and the number of ears per mu. Generally, the number of ears per mu is about 350 thousand, so the sowing amount is about 20 kilograms. If the soil fertility is poor or the soil moisture is poor, the sowing amount can be increased appropriately.
4. Early management. The endosperm nutrients of spring wheat are exhausted in the 3-leaf stage, and also in the ear differentiation and tillering stage, which requires a lot of nutrients. In spring, there is little rain, the wheat seedlings can't cover the ground, the ground is bare, and the soil moisture runs fast. Therefore, the management of spring wheat should be topdressing and irrigation early to promote early tillering.
The two leaves are watered with one heart, and 35 ~ 40 kg ammonium bicarbonate or 0/5 kg urea/kloc is applied in combination with the water with poor soil fertility, and fertilization is postponed until jointing stage when the soil fertility is good. In principle, the top water should be followed by the second water with an interval of 10 ~ 15 days. After the second watering, water it slowly for the third time. The third watering should generally be formed in the second internode, and it should be carried out after the ineffective tiller dies.
5. Good water for grouting. When grouting, be careful not to water in rainy and windy days to prevent wheat from lodging. After the wheat blooms, water is poured every 15 days or so.
6. Pay attention to insect prevention. Because spring wheat stems and leaves are tender than winter branches, they are more vulnerable to pests and diseases. Therefore, spring wheat should strengthen pest control more than winter wheat.
