Is rice resistant to high temperature? How to deal with the heat damage caused by high temperature? What's the impact?
The damage of high temperature to rice plant is closely related to the growth period of rice. Many studies have shown that during flowering, high temperature and heat injury will affect pollen maturation, anther cracking, pollen germination in stigma and pollen tube elongation, resulting in non-fertilization pairs.

Suitable conditions for growth of tea trees
The shape of heat is generally expressed by temperature, while the main factors affecting the growth of tea trees are air temperature and soil temperature. The biological lowest temperature of tea plant is generally about 10 ℃ (growth threshold temperature). The early bud species are less than 10 ℃, while the late bud species are higher than 10 ℃. The optimum temperature for the growth of tea trees refers to the most vigorous and active temperature of tea trees, which varies with different varieties and producing areas, mostly 20 ℃ ~ 30 ℃. The temperature difference and the temperature difference between day and night directly affect the accumulation of photosynthetic matter. The temperature is high during the day, and the light and matter are combined.

Four effects of High temperature on Rice
The temperature requirements of rice are different in each growth and development stage, and there is an optimal temperature. If the critical temperature exceeds the upper or lower limit, the growth and development of rice will appear abnormal phenomenon, that is, physiological obstacles. Therefore, attention should be paid to the effect of high temperature on rice. 1. Effect of high temperature on each growth stage of rice. 1. Heading and flowering stage. Generally, the temperature of 25-30 ℃ is suitable for rice at heading and flowering stage. A large number of empty grains will appear when the temperature is lower than 25 ℃ or higher than 30 ℃. At the same time, the high temperature

Planting techniques of pollution-free Lentinus edodes
Fungal mushrooms include straw mushroom, chicken leg mushroom, Lentinus edodes, Pleurotus ostreatus and so on. Lentinus edodes because of its delicious taste, loved by the public, plus its high sales price, planting management technology is easy to learn and understand, farmers are very suitable for planting and cultivation in autumn and winter idle season. 1. Bacterial bag production 1. Raw material preparation: Mulberry branches, apple branches or other broad-leaved trees such as poplar, willow, paulownia and locust can be used as culture materials, as long as they are not moldy and can be used after crushing. 2. Selection of cultivation period: the best season is from late August to mid-September. The highest ten-day qi

Culture methods of Chrysanthemum morifolium
Humidity management likes higher air humidity, and too low air humidity will accelerate the withering of a single flower. Also afraid of rain, need to keep the leaves dry at night, the optimum air relative humidity is 65-75%. Temperature management likes warm climate, avoids extreme heat, and obviously grows poorly when the summer temperature is higher than 34 ℃. It is not resistant to frost.

Summer Cultivation Technique of High Temperature Pleurotus ostreatus
With the coming of summer, the temperature rises gradually and the edible fungi on the market decrease day by day. At this time, the cultivation of high-temperature Pleurotus ostreatus can obtain considerable economic benefits. Variety selection. The main characteristic of high temperature type Pleurotus ostreatus is high temperature resistance. Generally, varieties with high temperature resistance of 36℃ can be selected. The high temperature varieties commonly used now include 831, Shuangkao No. 3, etc. Planting methods. Summer cultivation is generally suitable for indoor cultivation, so it is easy to control humidity. Bed width 80~100 cm, layer spacing 60 cm, can be set up 6~7 layers, bed room

Cultivation techniques of tea plant
Temperature is the basic condition for the life activity of tea trees. It not only affects the geographical distribution of tea, but also restricts the growth rate of tea. The effect of temperature on tea tree is mainly manifested in two aspects: air temperature and soil temperature. Air temperature mainly affects the growth of aboveground parts, while ground temperature mainly affects the growth of roots. But air temperature and ground temperature are interrelated. As far as temperature is concerned, tea trees from the tropics to temperate zones can adapt widely. But as far as growth is concerned, there are three basic points of temperature, that is, the threshold temperature for the growth of tea trees, suitable temperature and low temperature.

A brief discussion on the vernalization of Chunlan
The orchid that needs vernalization refers to the bud period of pregnancy, and the orchid that does not come to the bud does not need vernalization. The large temperature difference between day and night is a necessary condition for good opening. Yang vernalization, Yin flowering, high quality (this is suitable for Jiangsu and Zhejiang generation natural vernalization); if like the northern indoor vernalization recommended vernalization (temperature control at 1: 12 ℃, should have 10 ℃.

Which is more resistant to high temperature, red axis corn or white axis corn?
This question is the same as "people with single eyelids grow taller or people with double eyelids grow taller". There is no inevitable connection between the two. But whether it is the red axis or the white axis, the one that can withstand high temperature is the good axis. Let's take a look at corn in Huang-Huai-Hai area.

Analysis and Countermeasures of Meteorological Diseases of Pleurotus ostreatus
The cultivation practice of Pleurotus ostreatus for many years has proved that the abnormal sharp rise or sudden drop of temperature in spring can cause the same meteorological disease of Pleurotus ostreatus in the same climatic area. if it is poorly managed, a large number of wilting and death will occur in the fruiting body of Pleurotus ostreatus within 1-7 days. heavy losses. Therefore, it is of great practical significance to study the meteorological diseases of edible fungi, make use of the weather forecast results and formulate effective defense measures to reduce the loss of edible fungi and improve the economic benefits of growing mushrooms. 1 typical case and analysis 1.1 typical case 1:1
