What are the characteristics of clayey soil? What is the right thing to grow? Clayey soil is a kind of soil with low sand content, fine particles, slow water infiltration, good water retention and poor ventilation. If the clayey soil is very wet clayey soil, wetland plants can be planted: Reed, cattail, Chimonanthus, Cigu, Xie Ze, and so on.

Clayey soil tillage layer is soft, accompanied by moderate soil texture, good structure and permeability, suitable tillage, rich in plant nutrients. The following is to learn the clay that Xiaobian carefully arranged for you is suitable for planting plants, let's take a look.

A plant suitable for planting in clay.

Clayey soil is suitable for growing lotus, honeysuckle, Reed, banyan, crape myrtle, willow, rice, Sagittaria, wheat, broad bean and so on.

The method of planting rice

1. The purpose of rice tillage and soil preparation is to create a good soil environment for the root development of rice by means of ploughing and raking. It makes the rice seedlings develop rapidly after planting, absorb water and nutrients quickly, set up seedlings quickly and tiller early to form a high-yield seedling frame.

Second, the general east-west direction of cultivation is better than the north-south direction, which is related to the sun rising in the east and setting in the west. The main manifestations of the east-west direction are as follows: the first is to improve the light state of rice plants and improve the photosynthetic efficiency. Second, it improves the microclimate in the field, which is beneficial to the increase of water temperature and ground temperature of paddy field, and promotes the growth and development of paddy plants.

Third, the quality of rice transplanting has a great influence on the rooting and turning green of rice seedlings, and the early and late yield of tillers. Attention should be paid to shallow, straight and steady planting, including mechanical transplanting. The advantage of shallow transplanting is that it can make the root nodes in the shallow soil layer with high soil temperature, which is beneficial to the nutrient absorption and growth of roots, and can promote the occurrence of tillers.

Fourth, when paddy fields are planted year after year, it is not only necessary to absorb a large amount of trace elements such as N, P, K from the soil every year, therefore, the supplement of inorganic fertilizer alone can not meet the needs of rice production, and the combined application of organic fertilizer and inorganic fertilizer must be carried out.

Fifth, timely early transplanting refers to early transplanting within the transplanting period. Timely early transplanting can promote early growth and prolong the vegetative growth period of rice. In particular, late-maturing varieties can get full tillering, timely early transplanting, sowing and cultivation of strong seedlings and reasonable sparse planting in order to obtain higher yield. Usually transplant rice seedlings early around the middle of May.

6. The modern high-yield cultivation of rice emphasizes the cultivation of strong seedlings with sparse sowing, good seedling quality and quick rooting after planting. No matter early, middle or late rice, there is no need to protect seedlings with deep water after planting. The best method is shallow water ploughing and leveling, shallow water planting, 5-7 days after planting, so that the field water dries naturally. In this way, the basic fertilizer is not easy to be lost, and the gas is more coordinated. Shallow water irrigation, water-air coordination, regulating fertilizer by water and promoting roots by gas are carried out. It is beneficial to the development of roots and tillers.

7. As the saying goes, "planting in May, not transplanting seedlings in June" transplanting rice has to go through a period of stagnation to a gradual recovery after planting due to plant injury, that is, the period of returning to green. It generally takes 5-7 days. For single-cropping rice, the tillering begins about 10 days after transplanting, reaches the peak tillering stage within 20-25 days, and reaches the highest tillering stage within 30-35 days. Generally, the whole field tillering stage is about 20 days, while the effective tillering period for tillering into panicle is only 5-10 days, and the longest is about 15 days. The growth of rice at tillering stage is shown in two aspects. One is the growth of leaves and tillers in the aboveground part, and the other is the growth of roots in the underground part, which forms a robust root system. Due to the differentiation and growth of a large number of vegetative organs, it needs more supply of nitrogen nutrition, which shows the growth characteristics of nitrogen metabolism in rice. Therefore, it is also called the growth period. Rice plants develop vigorously and absorb a lot of nutrients. It is the key period to promote early tillering and cultivate strong tillers. The sprouting, elongation and various physiological activities of rice roots need enough oxygen.

8. The largest amount of water is needed at jointing and panicle stage, which must be ensured to meet the water needs of rice. However, when rice enters the panicle stage, the temperature is generally high, the decomposition of organic matter is accelerated, the microbial activity is vigorous, and the oxygen consumption is high. It is easy to cause the accumulation of toxic substances that are not conducive to root growth, which requires that it can not be flooded for a long time. Therefore, in the water management of jointing and panicle stage, the shallow water layer should be properly established in the later stage. The pipe water method of old water and no new water is adopted to coordinate the growth of both above ground and underground until maturity, especially for large panicle varieties, it is not suitable to cut off water prematurely during the filling and fruiting period, so as not to reduce the yield. After yellow maturity, the physiological water requirement of rice decreases, generally draining and drying about 7 days before harvest, so as to facilitate the harvest.
