Ginger is a perennial herbaceous vegetable of the ginger family and the genus Ginger, which is cultivated as an annual in China and cultivated all over the south, and is a vegetable crop with good economic benefits. Ginger contains spicy and aromatic components, is a necessary reserve of condiments for families, in daily life, the need for ginger is not large, but it is also inseparable, in our village ginger farmers are calculated in this way, the yield of ginger per mu is about 2500 kilograms, is about 5 times the local corn yield, as long as the price of corn is the same, the profit is 5 times that of planting corn, there is a need to plant. The purpose of this study was to explore the importance of plantar fertilizer application and its effects on root development and stress resistance in ginger planting. As an important seasoning and Chinese medicinal material, ginger plays a pivotal role in agricultural production. However, the growth habits and physiological characteristics of ginger itself determine its high demand for soil nutrients, so it is particularly important to apply foot fertilizer.
Ginger has an underdeveloped root system, poor drought resistance and waterlogging tolerance, ginger is a shallow root crop, the root system is underdeveloped and relatively fragile, which makes ginger susceptible to external environmental changes. On the one hand, the root system is not strong, which leads to the weakening of water and fertilizer absorption, and on the other hand, due to the limited rooting depth, it is easy to cause the growth of some plants on the ground to be too luxuriant, which affects ventilation and light transmission, and then leads to the occurrence of diseases and pests. Appropriate application of base fertilizer can stimulate the growth of ginger roots, improve the number and quality of hair roots, and enhance the ability to absorb water and nutrients. In particular, organic fertilizer can effectively improve soil structure, increase aeration porosity, and facilitate root extension. In addition, appropriate supplementation of trace elements such as zinc and molybdenum can also promote root differentiation and growth, so as to provide sufficient nutrients for the aerial parts. Therefore, the requirements for water in ginger growth are more particular, and the soil is too dry or too wet during the growth of ginger, which is not conducive to the formation and expansion of ginger blocks, and it is easy to cause disease and decay.
The land used to grow ginger must be deeply turned and exposed to the sun to make the soil weathered and loose, so as to facilitate the growth and development of ginger's root system. The yield of ginger is high, the growth period is long, so the amount of basal fertilizer required is more, 2000-2500 kg of rotted cattle and pigsty fertilizer should be applied per mu, 50-100 kg of fermented cake fertilizer and 50-100 kg of phosphate fertilizer. Or 70-80 quintals of human and animal manure with high concentration as base fertilizer, you can also increase compound fertilizer by 20 kg, and the planting effect is better. Proper supplementation of trace elements such as zinc and molybdenum can also promote root differentiation and growth, thereby providing sufficient nutrients for the aboveground parts. Proper application of phosphorus and potassium fertilizers can help improve ginger yield and quality.
During the growth of ginger, it is necessary to determine the top dressing according to the growth of the plant, generally 2-4 times, combined with cultivating and weeding, and it is necessary to master the topdressing method of first light and then thick. In the early stage of growth, because the plant is not large, the fertilizer needed is relatively less, generally less to be applied, to the middle and late stage of growth, the plant grows, and the underground part begins to pass through the ginger block, the fertilizer needs more, it is necessary to apply more diligently, you can add about 0.5% compound fertilizer in human and animal manure water, and fertilize it in sunny days that can be used as fertilizer and can be used as water, and the effect is better.
In summary, the application of base fertilizer should be paid attention to in the process of ginger planting to optimize the physical and chemical properties of the soil, cultivate a strong root system, and improve the ability to resist natural disasters. Of course, the specific amount and proportion of fertilizer need to be scientifically adjusted in combination with local climatic characteristics, soil conditions and ginger varieties. I hope this article can bring some inspiration and help to the majority of ginger farmers.
