How to grow rice in dry land? How to grow dry rice

1.Reasonable selection of land preparation. For dry rice farming, it is advisable to choose low-lying and flood-prone fields or water-retaining meadow soil and flat land.

Dry rice farming is not suitable for sloping hills, sandy or saline-heavy plots. Land preparation, especially the water-to-drought plots, advocate mechanical deep ploughing, and then carry out rotary tillage, so as to achieve a flat field, solid on the top and a virtual bottom, and the top of the land preparation can be carried out, which can keep the slurry water and improve the soil moisture.

2.Reasonable selection of varieties. The varieties required for dry farming of rice should have the characteristics of drought resistance, cold resistance, disease resistance and lodging resistance, moderate growth period and high yield. The growth period is 10-15 days earlier than that of local varieties.

3.Reasonably determine the sowing date. The germination temperature of rice was 10 12, and the sowing date was mainly under the condition of good soil moisture, and the moisture was mainly under the condition of drought.

When sowing, step on the upper and lower lattices, and do not step on the upper lattice when the moisture is large, so as to prevent the soil clay from affecting the emergence of seedlings. Sowing is mainly based on manual strip sowing, and wheat seeding machine can be used to sow when conditions permit, saving labor and effort. Covering depth 2, 3 cm.

In order to ensure the whole seedling, dry the seeds for 2 to 3 days before sowing, and mix the seeds with pesticides, and advocate the use of rice dry cropping seed coating agent coating, but do not soak the seeds under drought conditions to prevent reducing the emergence rate.

4.Reasonable dense planting. Dry farming rice has a short growth period and few tillers, and mainly depends on the main stem to form an ear. Increasing yield by panicle is the main measure for rational and dense planting of rice in dry farming. Generally, the sowing row spacing is 30 cm, the sowing amount per mu is 7 9 kg, and the seedlings are 150,180,000.

5.Strengthen fertilizer and water management. The role of fertilizer with water is very obvious, and the principle of fertilization is to base fertilizer as the main fertilizer, supplemented by top dressing.

The base fertilizer is mainly farmhouse fertilizer, and the amount of chemical fertilizer is increased, that is, 60% nitrogen fertilizer, all phosphorus, potassium, and micro fertilizer are used as base fertilizer to ensure nutrients and promote early growth and rapid growth of roots. Top dressing is applied twice, that is, tillering fertilizer and ear fertilizer, if there is no lack of fertilizer, it can not be chased or less chased to prevent late maturity. The water demand period and the critical period of water demand for rice coincide with the rainy season in January, and the normal annual situation can be met by natural precipitation.

In case of special drought years, it is necessary to properly replenish water to ensure high and stable yield.

6.Pest and disease control. Dry rice farming also needs to pay attention to the prevention and control of seedling disease, blight, rice blast, rice planthopper, rice leaf roller borer and other pests and diseases.

The prevention and control of mole crickets is coated with a special seed coating agent for rice, and it can also be trapped by poison grain. The method of preparing poison grain is to use 5 kg of soybean cake residue or corn bran per mu, add a little leek and add 25% chlorpyrifos wettable powder kilogram after frying, add 1 kg of water and stir evenly, simmer for 2 hours and put it into the field in the evening. Chemical weeding, post-sowing pre-seedling soil treatment to enclose weeds in 5 7 days after sowing, spray soil with 200 ml of 60% butachlor EC plus 200 ml of 200 ml of oxachlor EC 75 kg of water per mu; After seedlings, stem and leaf treatment weeds were sprayed with 60 kg of water with 200 ml of 60% butachlor EC and 200 ml of 20% propanium EC per mu before 5 7 days after emergence and 2 leaves of barnyard grass; 5. If there are broad-leaved weeds after the leaves, you can spray it with 20% dimethyltetrachloride water agent kilograms.

The land preparation is deeply cultivated 25 cm, and the land is finely prepared after ploughing; Before sowing and sowing, dry the seeds on a sunny day for 1 to 2 days to remove the grain and debris; Soak the seeds with water for 12 to 24 hours, then soak the seeds with 300 times of strong chlorine or carbendazim solution for 12 to 24 hours, wash the seeds with clean water after disinfection, and soak the seeds for 24 hours after disinfection.

1. Plot selection: use fields with sufficient soil fertility and convenient drainage and irrigation. 2. Seed treatment:

Soak the seeds in disinfectant water and place them in a tray to raise the seedlings. 3. Planting method: Take the seedlings out of the soil and then transplant them into the soil.

4. Field management: water frequently during high temperature and drought, and apply compound fertilizer in the peak growing season.

1. Plot selection

Upland rice likes to grow in fertile and breathable soil, so when planting, it is necessary to choose fields with convenient drainage and irrigation, rich organic matter, and apply well-rotted farmhouse fertilizer, and then turn the soil liquid to make upland rice grow strongly.

2. Seed treatment:

Before sowing upland rice, be sure to soak the seeds in disinfectant water for bifiscopy disinfection, and then prepare a seedling tray, put 2-3 seeds in each small hole, control the temperature at about 20 degrees Celsius, and the upland rice will sprout after about 2-3 weeks.

3. Planting method

When the dry rice grows to about 10 cm, it is necessary to move the seedling tray near the prepared field, remove the seedlings from the soil, and then plant them in the field in rows, and finally water the dry rice enough to moisten the soil.

4. Field management

In the process of breeding dry rice, it is necessary to water according to the weather changes, and in the summer high temperature season, the water evaporates quickly, so it is necessary to irrigate the field frequently, and in order to improve the yield of dry rice, compound fertilizer and organic fertilizer need to be applied.

Summary. Dryland rice planting: Dryland rice seeds need to be sterilized (soaked in disinfectant) before sowing rice

Dryland rice planting: Dryland rice seeds need to be sterilized (soaked in disinfectant) before sowing rice

Prepare a (rice seedling) tray, (each) hole can put 2-3 rice seed mold songs, keep the ambient temperature of the surrounding denier cover at about 20 degrees cherry blossom cover. In general, after about 14-20 days, the seeds will sprout.

When the rice seedlings grow to a height of 10 cm, you can transplant the rice seedlings in the seedling tray and plant them in the prepared dry land, and water the rice in time after planting to avoid the soil being too dry, which is not conducive to the growth of the seedlings.

1. Find a suitable sowing area.

Since upland rice is a semi-arid and half-water plant, it is most suitable for planting in areas where water is scarce, commonly known as the harvest of the sky, and in low-lying areas where other dry crops are susceptible to waterlogging. Upland rice and wheat planting are the same as dry sowing, and as long as the soil has moisture throughout the growing season, there is no need to circle water in the field for maintenance.

2. Soil preparation and fertilization.

Land preparation requires refinement, deep ploughing, harrowing, flattening and other work, deep ploughing depth of about 20cm, pay attention to removing large soil clods in the field. Fertilization should be applied to the bottom of the plant, and the conditions for applying farmhouse fertilizer can make the combination of farmhouse fertilizer and chemical fertilizer, rice is relatively sensitive to nitrogen, and the amount of phosphate fertilizer and potassium fertilizer should not be too small.

3. Sow seeds at the right time.

In the middle and lower reaches, early rice is generally sown in late March and early April. Before sowing, the rice seeds should be left to dry in the sun for three or four hours, and the sun's ultraviolet rays can kill some germs and viruses on the seed husks. There are two types of sowing in drylands:

One is manual sowing, and the other is machine stripping. The sown upland rice is relatively uniform, but the amount of seeds is slightly more, the bottom fertilizer should also be sprinkled, and the fertilizer utilization rate of strip sowing is higher.

4. Reasonable irrigation.

Although it is upland rice, it is also necessary to carry out reasonable irrigation to ensure the water absorption of upland rice during the growth process, but do not flood irrigation, and irrigate when there is drought in the field.

5. Top dressing and weeding.

When the seedlings of upland rice grow to about 20 days, they officially enter the tillering stage. In order to make it have enough nutrients and more tillers, it is necessary to apply fertilizer once, which can be about 18 20 catties of urea per mu.

6. Pest control.

Common pests and diseases are rice blast and borer. Rice blast control: spray evenly with 40% rice blast wettable powder 400 times liquid + 2% spring budmycin water solution 500 times.

Upland rice is a rice variety that is cultivated in arid regions. It adapts to drought, little rain and other environments, and has the characteristics of water saving, drought resistance, cold resistance, and disease resistance. The following is how to grow upland rice:

1.Choose land: Choose soil with deep soil, good drainage and high fertility, and avoid planting upland rice in low-lying or flood-prone areas.

2.Land treatment: ploughing, raking, and leveling are carried out in the spring to remove weeds and make the land fully breathable and soft.

3.Sowing: Sowing in early spring or late autumn should be carried out with high-quality seeds and pre-treated.

When sowing, you should be cautious to control the depth, avoid too shallow or too deep, generally the depth is 3-5 cm. 4.Fertilization:

Basal fertilization is applied before sowing and then topdressing is carried out during the growing period to ensure the growth and development of upland rice. 5.Management:

Upland rice needs to be managed during the growth period, including watering, weeding, fertilizing, and pest control. 6.Harvest:

Upland rice is generally harvested in August and September, and attention should be paid to protecting the rice ears during harvest to avoid losses. It should be noted that the cultivation of upland rice needs to fully consider the local climate, soil, water resources and other factors to ensure the growth and development of upland rice.

Summary. Dear, upland rice should not be cultivated as rice in paddy fields. Growing upland rice in paddy fields has the following problems:

1.Restricted growth rate: Upland rice growth may be limited due to the moist environment in the paddy field, as upland rice grows faster when exposed to sufficient moisture.

2.Water quality issues: Paddy fields may have problems such as pollutants or weeds, which may lead to poor growth of upland rice, which may affect the results during flowering and fruiting.

3.Diseases caused by improper handling: Chemical pesticides in paddy fields and non-herbaceous crops such as long-term soaking cotton strips may adversely affect the plants, causing diseases or impurities.

Okay, got it.

The growth habit of rice is to like high temperature, humidity, short day, the soil requirements are not strict, the seedling germination temperature is 28-32 °C, and the average daily temperature of tillering is more than 20 °C. Because rice seeds have the law of wet long buds, dry long roots, and cold long buds, seed germination is generally carried out in two stages after the completion of seed soaking. After the rice is planted, it must be mulched, especially when sowing spring seedlings in early spring, this stage is even more important.

1. Rice habits

1. The growth habit of rice is to like high temperature, humidity and short day, and the soil requirements are relatively low. The appropriate temperature of seedling germination is 28-32 °C, the tillering stage is above 20 °C, the appropriate temperature of panicle differentiation is about 30 °C, and the branches and spikelets will differentiate and prolong at low temperature. The optimal temperature for heading of rice is 25-35 °C, the optimal temperature for flowering is about 30 °C, and the fertilization of rice will be affected when it is lower than 20 °C or higher than 40 °C.

2. Because rice seeds have the law of wet long buds, dry long roots, and cold long buds, seed germination is mainly carried out in two stages after the completion of seed soaking. The first stage is high temperature germination, the temperature can be mastered at about 30 °C, regularly sprinkled with water to turn the seeds, so that the temperature and humidity are uniform, about a day and night regret 80% of the seed grain will bloom.

3. After the rice is planted, it must be mulched, especially when sowing spring seedlings in early spring, mulching will be more important. The mulch can choose aged grass ash, fine manure soil, and tender milk vetch, and the seeds must be covered when mulching. Seedling mulching has the effect of keeping warm, cold, and birds, increasing nutrition at the seedling stage, and preventing salinity from rising, so if you want rice to grow better, you must cover it.

2. How to grow dry rice

1. Before planting dry rice, it is necessary to choose low-lying waterlogging fields or water-retaining meadows, and dry rice cannot be planted on slope land, sandy or saline-alkali plots. Before planting, the soil should also be prepared first, especially the water to dry plots, which can be used to turn deep and then carry out rotary tillage, and the land can be carried out on the top ridge, so as to keep the slurry water and improve the soil moisture.

2. The minimum temperature of rice germination is 10 °C-12 °C, and the sowing date is mainly under the condition of good soil moisture during sowing, and the moisture can be mainly used under drought conditions. When sowing, we must step on the upper and lower lattices, and do not step on the upper lattice when the moisture is large, so as to prevent the soil from affecting the emergence of seedlings.

3. The growth period of dry rice is relatively short, and there are few tillers, mainly relying on the main forest calendar stem into a bijin ear. Increasing yield by panicle is the main measure of reasonable and dense planting of rice in dry farming, the general sowing row spacing is 30 cm, the sowing amount per mu is 7-9 kg, and the seedling protection is 15-180,000 plants.
