Soon to the valley rain, many areas have begun to prepare to plant beans and a variety of fruits and vegetables, whether planting or transplanting, the growth is good or not, flowering and fruiting are not much, mainly in the seedling management, seedling growth determines the yield in the later stage. If the seedling stage is well managed, the seedlings will grow strongly, the flower buds will differentiate, flowering and fruiting will be smooth, the fruits will naturally be more, and the yield will naturally be high. If the seedling management is not good, the seedling growth is weak, long, vigorous, etc., it will inevitably affect the differentiation of flower buds, even if it is flowering, sometimes it can not sit still and the fruit will fall when it grows. Therefore, no matter what beans and fruits and vegetables are planted, the following points must be remembered during the seedling stage.
1. Water control and squatting seedlings
Water control and squatting seedlings at the seedling stage is an important method to promote the development of root system and the robustness of seedlings, and it is also a solid foundation for more flowering and fruiting in the later stage. Because no matter what fruits and vegetables, in order to have a high yield, the seedlings must be strong. Therefore, regardless of beans or all kinds of melons, fruits, vegetables and fruits, after planting seedlings and transplanting seedlings, until before flowering, it is necessary to properly control water, and water control is to water less and let the soil be slightly drier, so that the root system can be rooted and developed, and the seedlings will grow thick and strong, so as to avoid the appearance of long growth and vigorous growth.
Second, the fertilization at the seedling stage should be balanced
Fruits, vegetables and beans not only need to grow seedlings, but also to carry out flower bud differentiation, and the nutrients required are also diverse, nitrogen fertilizer to grow branches and leaves, phosphorus fertilizer to promote flower buds, potassium fertilizer disease resistance and lodging resistance. Therefore, nitrogen fertilizer can not be used alone, nor can phosphate fertilizer and potassium fertilizer be used alone at the seedling stage, and nitrogen, phosphorus and potassium must be used together to promote the development and growth of roots, branches and leaves and flower buds. Again, too much nitrogen fertilizer at the seedling stage is easy to lead to the vigorous growth of seedlings, too much phosphate fertilizer and potassium fertilizer, it will inhibit the absorption of nitrogen fertilizer, under normal circumstances, nitrogen fertilizer accounts for two-thirds at the seedling stage, and phosphorus and potassium fertilizer accounts for one-third.
3. Timely replenishment of boron fertilizer and molybdenum fertilizer
Boron fertilizer plays a very important role in flower bud differentiation, pollen tube elongation, flowering and fruit setting in melon and fruit crops. If boron fertilizer is lacking before flowering, it will lead to poor flower bud differentiation, shortening of pollen tubes, poor pollination, flower and fruit drop, etc. And molybdenum fertilizer is indispensable for carob, which is the key to more flowering and more beans. Therefore, boron fertilizer should be supplemented in time at the seedling stage of melon and fruit crops, and molybdenum fertilizer and boron fertilizer should be supplemented in time from the seedling stage of beans.
Fourth, the seedling stage of diligent hoeing and loosening soil
Melon and fruit crops and beans, the seedling stage most like loose and breathable soil, loose and breathable soil can develop well, seedlings can grow well. If the soil surface is hard and compacted at the seedling stage, the first seedling is reluctant to grow, and the second is prone to stem base rot, standing blight and root rot and other diseases. You can test it yourself to know that the seedlings of the diligent hoe loosening soil grow quickly and well, and the seedlings that do not hoe the loose soil grow slowly and have many diseases. Therefore, the work of hoeing and loosening the soil at the seedling stage cannot be missing.
Fifth, avoid excessive watering at the seedling stage
Regardless of beans or melons and fruits, before flowering, it is mainly to promote roots and strong seedlings, and too much watering is prone to internode elongation, vigorous growth and longevity, resulting in flowers and fruits. In addition to transplanting the root water and slow seedling water, the soil is slightly dry after the seedling is slow, if the soil is wet every day, the root system only grows floating bark roots, does not grow deep roots, and the root system will not supply nutrients after fruiting, and it is easy to age, resulting in serious flower and fruit fall. Therefore, at the seedling stage, it is necessary not only to control water, but also to hoe and loosen the soil frequently, increase soil ventilation, and promote better development of the root system and the robustness of the seedlings.
The above is the key point of seedling management of beans and fruits and vegetables, and you can flexibly adjust the management method according to your actual situation and vegetable growth.
