Sorghum planting is a month late, how to make sorghum mature

Sorghum is widely cultivated in the north and is one of the common crops in our daily life, so let's take a look at the conditions under which planting can improve the quality and annual yield of sorghum.

1. Temperature. The optimal temperature for sorghum seed germination was 18 35 and the minimum temperature was 8 12. In the process of sorghum growth and development, if the temperature is too high, the seedlings will be tall and weak; If the temperature is too low, it will cause the seedlings to grow slowly.

The optimal temperature for the growth and development of sorghum seedlings was 20 25, and the optimal temperature for jointing and booting was 25 30. The suitable temperature for heading and flowering is 26 30. Too high a temperature will cause the pollen of some spikelets to become dry and ineffective, and low temperatures will cause the buds to not open, the anthers not to crack, the pollen amount to decrease, and the flowering period to be delayed.

2. Moisture. When the soil moisture content is 15%-20%, sowing can be carried out. The water requirement at the seedling stage accounts for 8% and 15% of the total water requirement during the whole development period.

The optimal soil moisture content is 50%-65% of the maximum water holding capacity in the field. The water requirement at the jointing and booting stage accounted for 33% and 35% of the total water requirement during the whole growth period. The water requirement at heading and flowering stage accounted for 22% to 32% of the total water requirement during the whole growth period.

Proper control of soil moisture at seedling stage is conducive to the healthy growth of sorghum. If there is a lack of water, it increases the number of sterile flowers, reduces the viability of pollen and stigma, and leads to poor fertilization. Excessive water at heading usually leads to branching and spikelet degradation under the panicle; Once there is a drought during the grain filling period, the grain yield will decrease; In the later stage of grouting and too much soil moisture, it will also cause turf to rot and even freeze damage.

3. Illumination. The lack of illumination during panicle differentiation mainly affects the number of grains per panicle. Insufficient sunshine or continuous rainfall during booting may lead to stunted development at the base of the spikelet and "baldness".

If sufficient light is obtained during the filling stage, the increase of grain weight can compensate for the decrease in grain count. In the later stages of growth, the function of functional leaves gradually declines, and higher light intensity is required to maintain a higher photosynthetic rate.

4. Fertilizer. From the early stage of growth, phosphorus has significant effects on the growth and development of sorghum, such as plant height, leaf emergence rate and leaf area. The jointing and booting stage is the period when the nutrient absorption is the fastest, the largest absorption and the highest fertilizer utilization rate, which is the first peak period of fertilizer absorption.

Top application of nitrogen fertilizer at jointing stage (early stage of panicle differentiation) had the best effect. Sufficient phosphorus** increased leaf area, fresh weight, root number and plant height per plant; When nitrogen, phosphorus and potassium are sufficient, it is conducive to the formation of more grain production. Adequate nitrogen in the late growth period helps to maintain and prolong the assimilation time of functional leaf area, and also helps to increase the protein content of grains.

Sorghum is a food crop, sorghum is suitable for growing in temperatures of 15 to 25 degrees. Sorghum can be grown in mountainous terrain at an altitude of 1 km to 3 km above sea level. Pay attention to regular weeding.

First of all, we should choose high-quality varieties, we should choose fertile soil, spray pesticides regularly, remove insect pests in time, and ensure sufficient light, maintain a suitable environment and temperature, and do a good job of drainage and ventilation.

Black soil should be chosen, and some good sorghum seeds should be chosen. When planting sorghum, a certain distance should be maintained. After planting sorghum, you can lay a layer of plastic film to water more and fertilize more, which is the best condition for planting sorghum.

First of all, when planting, we must choose the soil is more fertile and broad land, and we must use farmhouse fertilizer when fertilizing, do not use the fertilizer bought outside, and often water the plants, but also to prevent the occurrence of pests and diseases, if there are small insects, then we must spray insecticides in time. I think that if we can do these things well, we will be able to achieve the best conditions for sorghum cultivation.

When the temperature is right, it can germinate in three or four days, and it can grow 3-4 leaves in about 20 days.

Dear, I'm honored to have your question The information that the teacher found for you here is: sorghum can be planted for several years in a row, and sorghum can be planted for 5 years in a row. Sorghum should not be planted in heavy crops.

Sorghum, avoid heavy stubble and welcome stubble (only plant sorghum every other season). Sorghum has a well-developed root system and strong ability to absorb water and fertilizer, and in the case of no fertility supplement, the yield of sorghum planted year after year is bound to decrease. After sorghum is planted, pests and diseases will also accumulate, especially smut, grub and other pests and diseases.

The sorghum stubble was not cropped in the vegetable field with more fertilizer and soybean stubble with strong nitrogen fixation ability, followed by the absolute liter of potato, cotton, wheat, corn, millet and other crops. In addition, peanuts, sweet potatoes, buckwheat, tobacco, etc. are also good sorghum stubble. The common ways of sorghum rotation in northern China are:

soybean-sorghum; sorghum – millet; Soybeans - corn - sorghum, etc.

<> can be sown from mid-March to late June, and the corresponding ripening time is from early July to mid-October. Sorghum likes temperature and light, and the temperature required during the growth period is higher than that of corn, and has certain high temperature resistance characteristics, and the suitable temperature is 20-30 during the whole growth period. Sorghum seedlings are generally cultivated 2-3 times, the first time combined with seedlings, and the second time after 10-15 days.

The protein in sorghum rice is mostly alcohol-soluble protein, and there are few essential amino acids such as tryptophan and lysine, which is an incomplete protein that is not easy for the human body to absorb.

1. Sorghum matures in several months.

1. Sorghum can be sown from mid-March to late June, and the corresponding maturity time is from early July to mid-October. Sorghum likes temperature and light, and the temperature required during the growth period is much higher than that of corn, and has certain high temperature resistance characteristics, and the suitable temperature for the whole growth period is 20-30 °C. Sorghum needs sufficient light throughout the growth period, its root system is relatively developed, the root cells have a high osmotic pressure, and the ability to absorb water from the soil is strong.

2. Sorghum seedlings are generally cultivated 2-3 times, the first time can be combined with the seedling, and the second time is carried out after 10-15 days. Before and after jointing, it should also be cultivated once, and the cultivation should be combined with top dressing and soil cultivation, so as to promote the growth of sorghum at the same time, it can also enhance the windproof, anti-lodging and soil water storage and moisture retention ability.

3. The protein in sorghum rice is mainly alcohol-soluble protein, and there are few essential amino acids such as tryptophan and lysine, which is an incomplete protein that is not easy for the human body to absorb. Mixing it with other grains increases its nutritional value.

2. What can be used for sorghum after it is ripe.

1. Sorghum pasta.

1) Sorghum noodles are also known as wowotou, its color is yellow, the taste is relatively rough, and many people don't like to eat it.

2) But whole grains are very helpful to human health, so it is being valued by more and more people.

3) In the past two years, the planting area of sorghum = has been getting larger and larger, and it is mainly used as pasta by human food bonds.

4) In addition to being made into steamed buns, sorghum noodles can also be made into noodles and multigrain pancakes.

2. Sorghum snacks.

1) In addition to being used as pasta, sorghum can also be used to make some snacks, such as pot rice, hairy ears, etc.

2) Sorghum can be made into snacks through special processing, and it is also loved by many people.

3. Winemaking. 1) In addition to eating, sorghum also has a very large use for sake brewing, and the sake made from sorghum is also loved by many people.

2) Sorghum liquor must be of good quality, sorghum liquor is characterized by the fact that the wine manuscript is more fragrant, the wine made with rice will be purer, the wine made from glutinous rice is smoother, and the taste of rice wine is spicy.

Attention should be paid to the planting of sorghum: 1. Pay attention to the implementation of crop rotation and stubble. 2. It is necessary to sow early at the right time. 3. When sowing, seeds should be dressed. 4. After the seedlings are set, the seedlings should be squatted before jointing. 5. Reasonable watering and fertilization, and timely cultivation after watering.

Sorghum is one of the important food crops, sorghum grains can be eaten, wine, etc., and have high planting value. So how to grow sorghum? The following is an introduction to the method of sorghum cultivation.

The time when sorghum was planted.

The cultivation of sorghum can be divided into spring cropping and autumn cropping. The spring sowing period is about the end of March to the middle of April of the lunar calendar, the time should not be too early, because the early sowing temperature is low, the growth is slow, and it is easy to die in the cold snap, and the autumn crop is sown between the end of May and late June of the lunar calendar, and the time should not be too late, so as not to encounter low temperature in the middle and late stages of growth, affecting the growth and delaying the maturity period.

Methods of growing sorghum.

1.Land selection: sorghum root system developed water absorption and fertility absorption, it is advisable to choose flat, loose and fertile plots for planting, because of the characteristics of drought resistance, waterlogging resistance, salinity-alkali resistance and barrenness, so low-lying and waterlogged plots or barren and arid saline-alkali plots can also be planted, and the requirements for the previous stubble are not strict.

2.Land preparation: the quality of sorghum land preparation is the key to grasp the whole seedling and determine the yield, before sowing must be done fine land preparation, harrow flat harrowing fine, advocate autumn land preparation to ensure spring soil moisture, autumn ploughing, autumn harrowing, autumn ridges.

3.Crop rotation: sorghum should not be cropped, reasonable rotation method is the key to increase sorghum yield, the ideal stubble is soybean stubble, followed by corn stubble, potato stubble, etc., because of the sensitivity to pesticides, so avoid the use of long residual pesticides in the previous stubble.

4.Seedlings and seedlings: sorghum seedlings after 3-4 leaves during the seedling, 5-6 leaves of the seedlings, seedlings should be kept at equal distance and left strong seedlings, seedlings, seedlings, not double seedlings, two seedlings, should also be uprooted hybrids, improve purity, give full play to the yield increase effect of improved seeds.

5.Timely tillage: the first tillage of sorghum seedlings is combined with the seedlings, and the second tillage is carried out after 10-15 days, and the tillage should be combined with top dressing and soil cultivation before and after jointing, so as to promote the growth of sorghum and enhance the windbreak, lodging resistance and soil water storage and moisture retention capacity.

6.Irrigation management: The water requirement of sorghum seedling stage accounts for about 10% of the total water requirement in the whole growth period, 50% in the jointing and booting stage, 15% in the booting to flowering stage, 20% in the filling stage, and about 5% in the maturity stage.

7.Reasonable top dressing: do not expose the fertilizer to the surface of the ground when topdressing sorghum, and should be watered in time after top dressing.

After sorghum emerges, seedling fertilizer can be applied according to the emergence of seedlings; At the jointing stage of sorghum, 1000 kg of decomposed agricultural fertilizer and 10-15 kg of urea can be applied; 1000 kg of agricultural fertilizer and 20 kg of urea can be applied at the booting stage of sorghum; 1000 kg of agricultural fertilizer and 8-10 kg of urea can be applied to sorghum during the grain filling period; Potassium dihydrogen phosphate should be sprayed appropriately from heading to grain filling stage to promote early maturation and increase yield.

The above is the introduction of sorghum planting methods, friends who plant sorghum, you can refer to the above planting methods, according to the actual planting conditions, reasonable planting.

Sorghum is generally planted at the same time as corn, and the harvest is about the same. You can grow sorghum in the same way as corn grows.

The main reason is that now the wine is generally made of rice, and in the past, most of it was sorghum, and rice replaced sorghum, and there was an overproduction, and the peasants could not sell it, and it was worth growing slowly

Can the harvester still harvest sorghum.
