花生虽是抗旱作物,但在生育的关键时期若缺乏水分又未及时供应,就会影响正常发育,造成严重减产。经多年的试验研究证明,花生有两个浇水高峰期,第一个高峰是在初花期即开花水;第二个高峰是在结荚后期即饱果水。这就是花生高产栽培的“双峰”浇水法(见图)。其主要作用是:前峰促花下针,后峰促果饱满,中间低谷控棵徒长,以达到花多、花齐、果多、果饱的高产目的。花生在生长过程中遇旱浇水要因地制宜进行,在丘陵土层浅薄的瘦地块何时遇旱何时即可浇水;在土层较深较肥的地块,特别是高产栽培田,就不能在任何时候遇旱就浇水。高产田在初花期遇旱浇水可以促进开花下针,在7月中下旬和8月上中旬高温季节遇旱,则不急于浇水,否则就会造成徒长倒伏、早衰和烂果而大幅度减产。此时,可利用干
Although peanuts are drought-resistant crops, their lack of moisture and their timely supply during the crucial period of their fertility will affect their normal development and cause serious cuts in production. After years of experimental studies have shown that peanuts have two watering peak, the first peak is flowering in early flowering; the second peak is in the late pod that full fruit water. This is peanut high yielding cultivation “double peak ” watering method (see picture). Its main role is: before the peak to spend under the needle, after the peak to promote fruit full, the middle of the valley to control long and narrow, in order to achieve more flowers, flowers Qi, fruit and more fruit full of high yield purposes. Peanut drought in the process of growth due to local conditions should be carried out in the hilly soil shallow thin when when the drought can be watering; deep soil in the more fat land, especially in high-yield cultivation fields, We can not water any time of the drought. The drought-tolerant watering of high-yielding fields at the early flowering stage can promote the flowering of the lower needle. In the middle and late July and the middle of August, drought occurs in the middle and high temperature seasons, it is not in a hurry to water the water. Otherwise, it will result in significant long fall, premature aging and rotten fruit. Cut At this point, can be used dry
