Soil Management of Changing Citrus from Rice Fields in Red Soil

In recent years, many red rice fields in poor water conditions have been transformed into citrus. Many orange farmers believe that rice fields are farmland, fertile and well irrigated, and citrus species are ideal. In fact, the basic characteristics of red soil can be summarized as 6 characters: acid, thin, sticky, board, drought, and erosion. There are problems such as high groundwater table, shallow effective soil layer, thick clayey soil, easy water accumulation, poor soil structure, low ventilation performance, low organic matter content, and nutritional conditions that cannot meet the needs of citrus. In response to the characteristics and problems of rice fields in red soil, cultivated citrus should adopt the following measures:

First, reduce the water table. High ridge and deep ditch building. A 60-70 cm deep ditch is opened between each ridge or ridge to discharge the groundwater in the orange grove. It is better to reduce the groundwater below 1 metre. This will enable the deep rooting of citrus roots, increase the amount of hair roots, and contribute to the development of the root system.

Second, deep ravine. Open a ditch with a width of 80 cm and a depth of 1 m when constructing the garden, and lay 20 cm of straw or Other crop straw at the bottom of the ditch and backfill the topsoil. Afterwards, we can use the “hole” shape alternately deep ravines between the empty rows to fill the straw. We must not adopt a "planting tree method" for the fertile rice field (ie, we will dig into a hole and plant the seedling immediately).

Third, heap cultivation soil. The ditching soil is piled into a mound of 50 cm in height and 1 m in diameter on a planting hole, and the tree seedling is planted on the mound. Afterwards, the soil on the outside of the pile is used to cultivate the soil of the guest soil, the pond mud, and the ditch. , so that the soil thickening.

Fourth, grass cover. Saplings can be planted with plant garden flowers or white clover outside the canopy projection line, planted in October, grown in winter, and pressed in April the following year. Summer green manure can also be used to cover the garden soil.

Fifth, increase fertilizer material. After the colonization and survival, open the ring ditch along the canopy in winter and bury appropriate amount of compound fertilizer. In early July, the tip fertilizer was applied to promote early autumn shoots. Acidic heavy blocks are used to apply lime once and apply 150 kilograms per acre to neutralize the acidity of the soil.

Rice Huller With Polisher

Introduction:
The SB Rice Milling Unit is a kind of comprehensive equipment. Rice goes into machine via vibrating screen (removing stones) and magnet unit (removing little piece of steel), and then pass through hulling room (remove the yellow husks), winnowing room, milling room (remove the brown chaff, and then become white rice), and blowing room in turn. The machine can complete all the processing works from cleaning grain, hulling grain to milling rice. As to husk, chaff, blighted grain, as well as polished rice, they are all pushed out of machine separately. Furthermore, we add a jet blower near the outlet of finished white rice; it not only can drop down the temperature of white rice, but also can separate chaff from the white rice, and make the finished rice much clear.
