When will the rice be sown? Rice planting technology

When planting rice, the time for planting rice is different in the north and south. So, when is the rice planted? What are the rice planting techniques? Let's take a look at the planting time of rice and rice planting techniques in the north and south.


The growth habit of rice


Rice likes high temperature, high humidity, and short-day sunshine, and has no strict requirements on the soil, but paddy soil is the best. The lowest temperature for germination of seedlings is 10～12℃, and the most suitable temperature is 28～32℃. The average daily tillering stage is above 20℃, and the optimum temperature for panicle differentiation is about 30℃; low temperature prolongs the differentiation of branches and spikelets. The suitable temperature for heading is 25～35℃. The optimum temperature for flowering is about 30°C, lower than 20°C or higher than 40°C, and fertilization is severely affected.

Growth habits and planting methods of upland rice, rice and deep rice

Upland rice, rice and deep rice are one of the important food crops in our country. Today I will share with you the growth habits and planting methods of upland rice, rice and deep rice.


1. Upland rice, drought-tolerant, cultivated rice suitable for dry land cultivation, also known as upland rice, generally refers to cultivated rice that can adapt to growing in infinite dry land, sloping land and arid ecological environment. It is a variant of rice, and upland rice is also called drought-resistant rice. Different from the "rice" grown in paddy fields, upland rice does not need a water layer throughout its life. It is usually fed by rain after direct sowing on dry land or dry land, or supplemented with appropriate irrigation on this basis. But dry rice is not wheat or corn. Irrigation conditions must be available during special critical periods, otherwise it will have a great impact on yield. Although the growth of upland rice has similar light and temperature requirements to rice, its lifetime water requirement is about 2/3 or less than 1/2 of that of rice. If the weather is good, dry rice can not be watered during the whole growth period. However, if there is no effective rainfall for a long time and the farmland is dry, the "three times' ' irrigation is indispensable in any case, that is, the seedling water, booting water, and heading grouting water after sowing.  It is related to the timely emergence of all seedlings and full seedlings, and continuous drought after sowing affects both the emergence of rice seedlings and chemical weeding. ②Booting water: Drought at the booting stage can lead to small ears, a decrease in the number of grains in each ear, and even cause problems such as growth stagnation. Areas with good water sources should maintain a moist or shallow water layer at this time.


③Heading grouting water: lack of water at heading stage, slow heading, reduced seed setting rate, drought in the maturity stage, increased empty grains, reduced thousand-grain weight, and decreased rice quality, so irrigation is permeated at the beginning of the heading stage to ensure its water demand .


· Rice planting technology and management

Rice planting technology and management

The harvested rice grains are called rice grains and have a layer of shell. The shell is often removed together with the rice bran layer during milling. Sometimes a thin layer of glucose and talc is added to make the rice grains shiny. Rice with only the husk removed during milling is called brown rice, which is rich in starch, contains about 8% protein and a small amount of fat, and contains thiamine, niacin, riboflavin, iron and calcium. The rice from which the husk and rice bran are removed is called polished rice or white rice, and its nutritional value is greatly reduced.



Rice disease


The root causes of disease epidemics are: the proportion of high-quality susceptible varieties has increased, the physiological races of pathogens have increased, and the changes in farming and cultivation systems. 


· How should rice planting be managed?

Rice planting management is very important. Good management is very helpful to quality and yield. Today I will share with you how rice planting should be managed?


The management of rice planting can refer to the following methods:


1. Water-saving irrigation technology


Water-saving techniques should be used for irrigation during the growth period of rice. Irrigation and drainage should be carried out according to the water demand characteristics and requirements of each growth period of rice. It is mainly divided into deep water greening, shallow water tillering, deep water booting, earring, and diving maturity. During the re-greening period, since the roots of the seedlings are damaged during transplanting, they absorb less water, and the leaves have a large amount of evaporation, the seedlings must be re-greened in deep water after transplanting. To prevent physiological dehydration, the water depth should be about 2 to 3 cm. If the irrigation is too deep, the nutrient decomposition will be slow, which is not good for tillering; the booting stage is the period when rice requires a lot of water in the whole life, especially the meiosis stage, which is more sensitive to water response. At this time, lack of water will cause the spikelets to degenerate, resulting in short ears with fewer grains and more empty shells. Therefore, maintain a 2 cm water layer in the field during the booting stage.


2. Measures to prevent low temperature and chilling damage.

What is the prospect of rice planting in 2018? 2018 rice planting prospects and price analysis

For 2017, looking at the current market situation and rice planting costs, weather factors, pests and diseases, etc., below we will make a simple analysis of the prospects of rice planting in 2018, hoping to bring some help to farmers.


Looking at the price trend of rice in recent years, we believe that the price of rice will remain relatively stable and will not fluctuate greatly.


If farmers specialize in rice cultivation, scientific cultivation, and mechanization of science and technology, then rice cultivation is definitely profitable! But cost saving is the key to making money.
