Introduction of rice (1)

The introduction rules of rice and the main technical points of rice introduction are as follows: Any rice variety (combination) is formed under certain ecological conditions. The key to the success of the introduction is whether or not to master the characteristics of the temperature and light response of rice varieties, and introduce the ecological conditions of the region. And introduction rules. The introduction of rice has the following rules: (1) It is easy to achieve mutual success between regions with similar climates. All regions with similar latitudes and elevations have similar climates, and the temperature changes and length of sunshine are not much different. Therefore, mutual introduction is relatively easy to succeed. (2) Introducing species at different latitudes The varieties introduced at different latitudes should be selected for varieties that are insensitive to temperature and light and have wide adaptability. As long as the growing season can guarantee that introduction can generally be successful, southern rice varieties introduced into high latitudes in the north The introduction of early rice varieties is easier to succeed, but the growth period is slightly longer, the plants are relatively taller, the spikes are larger, and the grains are increased. With suitable cultivation techniques, high yields can be obtained. Late rice varieties are sensitive because of their short-day response, and they migrate southwards. They often cannot head crops when they encounter southern long-day sunshine conditions. If they encounter low temperatures, the seed setting rate decreases. Therefore, late-season rice cannot be cultivated in the Yangtze River Basin, and late rice in the Yangtze River Basin Can not be cultivated in the north. Rice varieties in the north of China were introduced to the low latitudes in the south, and the growth period of the varieties was generally shortened. It was appropriate to use the late-maturing varieties of the northern variety for mid-maturity or early maturing in the south, and it was easier to succeed. (iii) Mutual introduction between latitudes and different altitudes. When the temperature in high altitude areas decreases, the cultivated rice varieties are introduced into the low-altitude plain areas for cultivation, the growth period is shortened, and the temperature in the low-altitude plains is high. The cultivated rice varieties are introduced to the mountains in high altitude areas for cultivation. extend. China Agricultural Network Editor

Pizza Oven

Pizza ovens, as the name suggests, are primarily used for baking pizzas. It not only ensures that the pizza reaches the ideal degree of doneness in a short time, but also makes the crust of the pizza crisp and keeps the interior soft and moist, thus enhancing the overall taste and quality of the pizza. In addition, the pizza oven also has a variety of functions, such as roast meat, roast chicken wings, roast steak, etc., so it is widely used in pizza shops, bakery shops, burger restaurants, western restaurants and other places.
The working principle of the pizza oven is mainly based on hot air or high temperature heat source to bake the pizza. Depending on the type of pizza oven, it works differently. For example, a traditional pizza cellar oven uses wood or coal as a heat source to bake the pizza over a high flame. Modern pizza ovens may use more efficient and environmentally friendly heating methods such as electric heating, natural gas or air heating principles. Regardless of the type of pizza oven, the core goal of the pizza oven is to ensure that the pizza is heated evenly for optimal cooking results.
