In order to obtain high yields of rice, from the approach point of view, the number of panicles should be suitable first, and on this basis, high yields should be obtained by attacking large spikes. In order to obtain a suitable number of spikes, field management is a very important measure. By setting aside a field, the number of panicles can be controlled within a suitable range to prevent overshooting. In order to obtain big spikes, it depends largely on the use of panicle fertilizers, especially the promotion of flower-fertilizer. The precondition for the application of panicle fertilizer is to reduce the number of panicles through the field and fade the color of the leaves. In addition, the paddy field can also control the length of internodes of the base of the rice plant, which is conducive to improving the ventilation and light transmission conditions, improving the degree of stalk filling, and enhancing the lodging resistance.
In the production, the field should be treated as a high-yield measure and a fall prevention measure should be carried out in accordance with the requirements of “maturity to unequal time, time to timeâ€. As soon as possible, besides very few late plantings, late plantings, and poor emergence (not yet sufficiently seedlings) plots, the vast majority of fully-grown field plots must be immediately put on the field and cannot be waited any longer; To open the water hole and put it away, it is best to draw a ditch and put aside the fields, and at the same time clear the "outer three ditch," so that the water can be drained and dropped; the third is to be due to Miao and Yin Tian. For a long time, there are many seedlings, and the field of fertilizer should be re-shelved. The number of seedlings should be kept lightly. Fourthly, it must be done several times. The first time, it must be put on hold in the field and the field cracks. After the water continued to rest, until the end of July, until the white roots rise, the leaves rise, the color faded. After the field is kept, it is necessary to maintain a hard surface and the rehydration is not soft.
In addition, the use of relay fertilizers cannot be applied in mid-July, and the damage is considerable. The first is that a large number of ineffective deliveries occur, the group develops too many seedlings, the structure of the ear and grain is not adjusted, which is not conducive to high yield; the second is to lengthen the base 1 and 2 sections and increase the risk of later lodging; the third is to affect the application of panicle fertilizer and rice panicle fertilizer application The premise is that when the rice plant begins jointing, the leaf color must fade and yellow. At this time, if the leaf color does not fade, and the yellow panicle fertilizer does not fall, it will affect the harvest and yield. Therefore, in addition to very few individual seedling numbers and early application of a small amount of compound fertilizer to the depot, the vast majority of field blocks cannot currently be used as a relay fertilizer.

At present, with the exception of a few field plots with late planting, late planting and poor emergence, the vast majority of paddy fields in Hai'an County are already sufficiently seedlings. The focus of field management is to implement the practice of field pruning.
