Description

Straw land ditching, seed fertilizing and pipe burying mechanism

Technical Field

The utility model relates to a ditching is executed kind fertile pipe laying mechanism, concretely relates to is used for the grassland ditching to execute kind fertile pipe laying mechanism of improving machinery specially in grassland.

Background

Grass deterioration is now a problem of widespread concern and its progress has received widespread attention and research in governments and research institutes. The large-area grassland is seriously degraded, so that the ecological system of the grassland is unbalanced. In order to solve the problem, over the years, various national scholars actively explore effective recovery strategies of the grassland, and mostly concentrate on natural grazing land to utilize the basic ecological principle and method and comprehensively implement the measures of sealing and breeding, reseeding, irrigation, fertilizing, weed control, delayed grazing, loosening the soil and the like. Aiming at the grassland degradation problem, the grassland scientific research and production department researches and applies mechanical deep scarification, root cutting, reseeding, fertilization and pressing, and a whole set of operation technology is used for improving the degraded grassland. According to the investigation result, the subsoiler should meet the following requirements: 1. the maximum operation depth is 15-20 cm to reach the soil hardening depth, and a soil plate layer is damaged; 2. cutting off the root system of the perennial netted pasture to promote the tillering and propagation of the pasture; 3. after operation, the ground surface is flat (no upturned soil and no ridging is carried out), sand is not raised, and damage to vegetation on the ground surface is small; 4. does not affect the mechanized harvesting operation and the grass yield in the current year and strives to increase the yield. The soil plough layer structure is changed, the soil water storage capacity is improved, and the soil ventilation and water permeability is effectively improved; 5. and (3) the perennial leguminous or gramineous forage is reseeded, so that the excellent forage components in the degraded grass group are increased, the grassland vegetation coverage is improved, and the aims of improving the grassland productivity and the forage quality are fulfilled. The degenerated natural grass cutting field is improved and rejuvenated, the grazing pressure of the natural grassland is relieved, and the sustainable utilization of the grassland resources is realized.

The causes of grass deterioration can be explained in two ways, namely natural causes and artificial causes, natural causes being particularly important. Through research for many years, the most basic factor affecting the yield of pasture is the lack of soil water available for plant growth, and the increase of water in soil is necessary. As rivers on the surface of the grassland in northern China are rare, grassland irrigation conditions are not provided, the weather is extremely severe, the grassland is dry, windy and rainy, the annual rainfall of a large-area grassland is within 300mm, and the rainy season is mostly concentrated in 6-8 months. The green turning period of the pasture is a critical period of water demand and is a positive pasturing area drought period, and in the critical period, the pasture can be well irrigated once, so that the pasture yield can be improved exponentially. At present, in order to effectively improve the productivity of pasture, a large amount of capital is invested in some areas, and a large-scale spray irrigation machine is added to solve the problem that the pasture needs water in the growth period. Although the yield and the quality of the pasture are obviously improved, the production cost of the pasture is greatly increased. According to the preliminary measurement, only about 40-50% of water sprayed on the ground permeates into the ground and is supplied to the growth of the pasture. The rest of the rainfall is dry due to natural conditions and climatic characteristics of the pasturing area, the evaporation capacity is large, and most of rainfall is evaporated quickly; yet another portion of the precipitation is removed from surface runoff. Furthermore, the underground water in the pastoral area is buried deeply and mostly below hundred meters above the ground, the requirement on the water yield of a motor-pumped well matched with a large-scale sprinkling irrigation machine is very high, the water yield of the motor-pumped well is generally required to reach 150 plus 200t/h, a large amount of energy is consumed for water lifting and sprinkling irrigation machine driving, the investment on machines and tools and the consumption of electric energy are high, the cost of pasture is greatly increased, and the pastoral area lacking water resources is difficult to bear. Therefore, water-saving and power-saving drip irrigation equipment is urgently needed by farmers and herdsmen, and a combined operation machine capable of completing soil loosening, root cutting, reseeding, fertilization, drip irrigation pipeline laying and pressing at one time is provided.
