Sowing of spring crops must ensure quality
This is the key start-up period for the spring crop planting cycle. In the cultivation of modern intensive crops, “sowing†should neither be widely cultivated or harvested, nor can it be done by relying on lazy people. From the beginning, we must pay attention to the quality of spring crop sowing. The successful experience of modern high-yield cultivation is "seven-minute, three-in-one". As the saying goes: “There is money to buy seeds, and no money to buy seedlingsâ€. Only good seedlings can grow seedlings. With good seedlings, there will be a good harvest. If it is not good, one year will be delayed. Therefore, we must remind farmers once again that the spring planting must be well-grounded before it can begin sowing. As the farmer said: The roots of cotton are ploughed deeply. This shows that the soil preparation prior to planting should be such that the ground is flat and the tightness, fineness, moisture, air, temperature, and nutrient conditions of the root layer can be optimized and then sown. In other words, the entire planting process is carried out in two steps. The first step is soil preparation and the second step is seeding. Land preparation is divided into two parts. For one thing, the cultivation of ploughed soil requires a depth of 15 to 25 centimeters. The main measures are: 1. Plowing and turning the soil with a ploughshare. 2. Deep plowing, loosen the soil with shovels. 3. Rotary ploughing, the soil is chopped and mixed with a rotary ploughshare coulter, and it plays the roles of smashing, loosening, mixing and flattening the soil. Only the depth of the rotavator operation is shallow, generally about 10 to 12 centimeters, but the three operations of plough, hoe and leveling can be completed at one time. Root tillage should be carried out at the same time as the basal application and closely matched with the basal fertilizer, preferably organic fertilizer and compound fertilizer, and the fertilizer should be applied to a certain depth by ploughing or rotary tilling and mixed with the soil. Second, the general depth of topsoil cultivation should not exceed 10 cm, including measures such as flooding, flooding, and suppression. The experienced farmers' friends all know that the functions of flood control, flood control, and repression are very important for drought protection. For example, "the top of the river, water conservation and conservation," "intensive cultivation, no rain, no fear," "before planting." Bao Yu, after rolling solicitation, etc. In short, the role of soil cultivation is multi-faceted. It can not only improve the structure of the plough layer, but also adjust the proportions of solid, gas, and liquid phases, so that the water and fertilizer status of the farmland soil can reach the best state, and the root growth resistance can be reduced, especially the soil. Combining tillage with organic fertilizer and compound fertilizer makes the effect of maintaining fertilizer and supplying fertilizer better. In addition, land preparation can achieve the purpose of water conservation, which not only accepts rainwater but also reduces evaporation, runoff and leakage. As the saying goes: “It's really nothing to hide and the topsoil is sealed against evaporation.†Therefore, it is necessary to advocate land preparation before spring sowing, especially if there are no plots for autumn tillage, we must first spring and then spring. In order to guarantee the quality of sowing, it is necessary to promote land preparation as the first step, and to lay a good foundation for the harvest of summer and autumn. The second step is to enter the sowing stage. Generally, the requirements for sowing quality are: intensive tillage sowing, to ensure the number of basic seedlings, and at the same time require uniform distribution among the seedlings; in order to reduce atrophy, reduce the rate of weak plants, and improve the uniformity of the ear, must be done To: Evenly fertilize and spread poison baits before planting. 1. Select seeds. The grain size is uniform and the crushed grains are strictly eliminated. 2. Precision sowing. Do so consistently (3 to 5 cm) so that the seeds fall evenly. Strictly adjust the machinery, adjust the broadcast volume, and avoid the plugging of seeds, missing broadcast, and sowing. There is a dead end on the side of the land, which is caused by poor planting quality and lack of seedlings. The land should be broadcast first and then broadcast in the middle of Daejeon. When the rotary arable land is still to be used after sowing, it must be suppressed. After sowing, the machine should suppress the topsoil with short-tooth rakes, suppress the ridges after sowing, do not suppress ridge back, and keep the surface covered with rammed earth in the spring, which can play a good role in maintaining the ramming effect. Do a good job of pesticide seed dressing and soil disinfection, strict control of soil pests, to ensure seedlings full seedlings.
